After my recent popular post on 100 ways to spend a money free weekend, I received a most interesting comment from a Lifehacker reader named HFC:

It looks like a lot of free things are boring and/or require you to actually have friends. Aren’t there any fun things I can do by myself?

This comment really spurred my thinking. I’m a proud introvert - most of the activities I enjoy are either done alone or with a very tight group of friends. I don’t feel comfortable in large social situations, though I’ve learned how to cope well with them and not come off as a deeply antisocial jerk.

The only problem is that a lot of activities that you can do yourself require some money to enjoy. Renting a video costs money. Playing a video game? Very expensive.

Here are fifty suggestions for free or extremely cheap ways to spend your time. Some of these have appeared on other lists of free stuff to do before - others are new to this one. Similarly, some of these may appeal to you - others may not.

If you’re an introvert, have fun and save some money!

1. Make a collage postcard for PostSecret. For those unaware, PostSecret is a website to which people send postcards telling their deepest, darkest secret anonymously; the blog creator then posts images of some of those postcards on the blog. All you need is a blank postcard, some imagination, and a secret to tell. Look around your house for the materials you’ll need - old magazines are always a great place to start harvesting materials from. Look for images that reflect the secret you want to tell, then make a collage out of them on the card. Whether you mail it or not is up to you, but it’s a wonderful way to get creative and get some release on a secret you’ve been hiding.

2. Try out parkour. Parkour is essentially an athletic activity where you simply try to find the quickest path from point A to point B. You can do this pretty much anywhere - your yard, the park, anywhere in a city - and it’s always a lot of fun and good exercise. Plus, it’s an incredibly effective way to improve your mind-body coordination, as practicing this regularly will improve your balance and also your quick-decision skills.

3. Master a Rubik’s Cube. There are few parlor tricks that are more entertaining (for me, at least) than watching someone solve a Rubik’s Cube quickly. You can easily get ahold of one of these (ask on freecycle or Craigslist) - the trick is figuring out how to solve it on your own, then how to solve it quickly. Here’s a great guide for solving a Rubik’s Cube.

4. Make a list of all of the people who were a positive influence on your life and write them all a letter thanking them. Think for a bit about all of the people who have inspired you and helped you along in your current life path. Make a list of all of these people - mine, for example, includes my high school English teacher, some relatives and friends, and a few college professors. Then pull out some paper and a pen and write each of them a handwritten letter, reminding them of how they helped you out and thanking them for doing so. It’s a great way to get in touch with the people who helped shape your life, and it’s something you’ll feel genuinely good about for a long time.

5. Learn how to make string figures. I love making string figures. All you really need is a big loop of string and some imagination. Figuring out how to loop string around your fingers to make visual compositions of all sorts of things is a lot of fun. You can easily make spider webs, bridges, and other interesting things. Even better, learn about some of the cultural heritage of these string figures and try to relate the stories yourself as you make the figures. Here’s a guide to the basics.

6. Learn some basic yoga poses. Yoga is a great way to relax and meditate while stretching the muscles of your body and getting a surprisingly intense workout at the same time. Basic yoga is extremely simple and feels really good - a stretching routine once a day feels really good to me. Here’s a great introductory video to the very basics of yoga.

7. Take a free online class to learn the basics of a new topic. MIT’s OpenCourseWare offers complete downloadable lectures on a ton of different topics, starting from the most introductory areas to rather advanced topics. Want a starting point? Try microeconomics, macroeconomics, western philosophy, introductory physics, or, my personal favorite, video lectures on differential equations (though that one may not be for everyone).

8. Teach yourself how to cook. Not only is cooking the most cost-effective way to provide sustenance for yourself, it’s also an art form that rewards experimentation and practice. Challenge yourself to assemble an interesting meal out of the materials you have on hand. You might just find that it’s fun, that you’ve learned something new, and you’ve created something tasty to eat for just pennies.

9. Take a walk in the park. Likely, there’s either a park or a secluded rural area within walking distance of where you live. Set out on foot to go there, then just wander around enjoying what you can observe and take in. Enjoy the natural beauty around you. Even better, find a nice secluded place and engage in another of the activities on this list in a wonderful natural environment.

10. Listen to a podcast. Podcasts are wonderful snippets of intelligent (mostly) and engaging talk radio, where people pour out their hearts and ideas for you to hear - for free. All you have to do is find them and download them. To get started, try downloading a podcast receiving program to collect them for you - I quite like Juice. Here are ten podcasts I quite enjoy to get you started: The Splendid Table (on food topics), Marketplace (on economics and business), Speaking of Faith (on religion), Fresh Air (interviews of general interest), This American Life (quirky general interest stuff), This Week in Tech (technology news), Car Talk (automotive news and tips), Keith and the Girl (pop culture), Free Talk Live (non-partisan politics), and Nobody Likes Onions (comedy).

11. Learn a simple papercraft. Papercraft includes everything from origami (and neat things like paper snowflakes) to full paper models of … well, anything. The excellent OrigamiVideo.net has a huge collection of videos on how to get started making almost anything origami (and many other papercraft projects, too).

12. Do a crossword or a sudoku puzzle. Paper-and-pencil puzzles are a great way to stretch your mind in new directions. You can easily get them for free - the New York Times gives out a free crossword each day, an excellent free British-style cryptic crossword from The Herald, and a huge number of free sudoku puzzles at WebSudoku should provide you with more than enough puzzle-solving pleasure for a long time.

13. Teach yourself solitaire (or a solitaire variant). All you need is a deck of cards, a logical mind, and plenty of spare time. Klondike is the most well known one, but there are a lot of fun solitaire games out there: Freecell, Golf, Patience, and Beleaguered Castle. There are many others - here’s a sampling of ones to try.

14. Put some positive affirmations around you. On a series of Post-It notes, write down ten or so positive things about yourself (I find writing down positive memories is a great way to go, ones that put a smile on my face), then put them in places where you go irregularly and post them, like a rarely-used supply closet or the inside of your car’s trunk. Then, when you find them, they’ll lift you in a positive way. You could also do the same thing for someone you care about, posting some little reminders of their qualities in places where they’ll discover them.

15. Start a blog on a topic that fascinates you. If there’s a topic that fills you with passion, consider starting a blog on that topic. It’s easy (and free) to get started at Blogger or WordPress. Whenever you have an interesting idea about your topic or just get a strong desire to explain the basics, write it all out and post it there. It’s a great way to organize your thoughts and channel your passion on a particular topic.

16. Watch an old movie from your collection. Almost everyone has some old movies lying around. Dig some out and watch them. I find it particularly enjoyable to watch old home movies - videos of when my son was a newborn, for example, are particularly fun to pull out. I also enjoy watching movies that I dearly loved ten years ago but haven’t watched in years - I now see many of them as goofy fun for a rainy afternoon.

17. Teach yourself a card trick. Card tricks are a particularly fun way to entertain people in almost any situation, and there are as many different card tricks as there are grains of sand on the beach. Pick up a deck of cards and invest the time to learn one cold so that if the opportunity ever offers itself, you can easily show off that trick. For starters, here’s how to do a clever and simple trick called Quick as a Wink.

18. Tour your neighborhood on foot. Most neighborhoods have many interesting secrets and things to enjoy and observe on foot. Just head out of your front door and wander wherever your spirit takes you. You’ll likely find all sorts of interesting things on your journey - places you didn’t know about before, interesting landmarks, beautiful sights, and perhaps an interesting free thing to pick up along the way.

19. Go stargazing. The stars in the night sky are one of the biggest reasons I love living in rural Iowa. I can look skyward any non-cloudy evening and see a sky full of stars. If you’re lucky enough to live in an area with a clear sky. spend an evening or two gazing at the stars. In particular, try to go outside on nights where a meteor shower is in progress, as that just adds to the beauty of the Milky Way. Also, look for a guide to the night sky for your local area - Weather Underground offers a great one.

20. Get your finances in order. While this might not seem like fun at first glance, having a financial plan can greatly reduce the stress of day-to-day life and also greatly increase the peace of mind. Spend some time reading up on personal finance, working through activities like 31 Days to Fix Your Finances, setting goals, understanding your current financial state, doing estate planning, defining a budget, and so on. It’s all worthwhile, all free, and all of it will add to your peace of mind.

21. Make a time capsule. Find an old shoebox, then go around your home and find items that clearly mark the reality of your day to day life - a newspaper, receipts, magazines, pictures, and so on. Put them in the box and when it’s got plenty of items in it, tape it up very securely and write a date in the future when you can open it - say, in ten or fifteen years. Not only is it fun to collect the items now, it can be really interesting to look through those items in the future, when not only your life has changed, but cultural touchstones have changed as well.

22. Find (and read) some free, alternative newspapers in your area. Most urban areas have a handful of free newspapers, supported entirely by advertising or by sponsorship, that often provide insightful and interesting reading. Look for ones in your area in the lobby of the local library, in the lobby of grocery stores, and at city hall. Collect them, then take them home for a nice reading. In my area, I have easy access to Toons (a collection of political cartoons), The Sun (community events), Cityview (an independent public affairs paper for Des Moines), and Juice (a twentysomething paper in Des Moines published by the Des Moines Register). All of these can provide worthwhile reading - and they’re all free.

23. Learn a musical instrument. This might not strike you as a free thing to do, but it’s actually surprisingly easy to learn how to play an instrument for free. You can often get basic instruments (keyboards, acoustic guitars, and sometimes other things) on Freecycle or Craigslist, plus there are countless opportunities online for basic lessons on how to play any number of instruments, as well as how to read music. All it takes to get started is some time and some interest.

24. Listen to your favorite music up loud (and let yourself dance to it). I love to turn the music up loud on occasion and bounce around to it (all in complete privacy, of course). Few things get me more pumped up than a really lively song and a bunch of moving around in rhythm to the music. For me personally, few songs get me bouncing around energetically more than AC/DC’s Let There Be Rock. But that’s just me - I’m sure you have your own favorites.

25. Visit the library. This one’s right in the middle of the list, but it’s one of the best free things for an introvert to do on the cheap. The library is a gigantic collection of free books, movies, music, magazines, and countless other things - all there for the borrowing. Plus, there’s usually a lot of activities there for the introvert, from film showings to recommended reading lists and community calendars. Stop by and see what things a library really has to offer.

26. Do a jigsaw puzzle. A jigsaw puzzle is a wonderful engrossing activity. My family used to traditionally cover the kitchen table with jigsaw puzzles for much of the winter, with everyone sharing in the puzzle-solving process. You can usually find them for free on Freecycle without any effort at all and they’ll give you many hours of solitary enjoyment.

27. Build a detailed family tree. Most people are aware of at least a couple generations of their lineage, but things often get confused when you get further back than that. Spend some time building a detailed family tree, starting with what you know and eventually adding your own research to the mix. Contact older relatives for assistance, then use resources like Ancestry.com to fill in more blanks. Add as much detail as you’d like or, even better, make it into a multimedia project on your computer, with pictures and other materials.

28. Teach yourself to meditate. For stress relief and aid for overcoming tiredness, few things work better for me than a short period of meditation. The easiest technique is to just sit in a comfortable chair, close your eyes, and focus on nothing but breathing slowly for a while. Breathe in slowly, hold it for a bit, breathe out slowly. Over and over. If you want to dig deeper, here’s a great introduction to meditation with some strong mental aspects to work on.

29. Read a book you’ve got on your shelf that’s unread. Most of us have a book or two around our home that’s unread - something that we’ll read “someday.” Let today be that someday. Dig out that book and give it a serious, long reading. Let yourself get lost in the book, no matter what it is, and see if you can get through it (or at least a significant portion of it) in one sitting. Getting lost in a book is one of my favorite experiences - and it can easily be a free one.

30. Start a workout program at home. A basic workout program doesn’t need to involve an expensive gym membership - it just needs to involve personal initiative. After all, many of the most effective exercises (running/jogging/walking, sit ups, prone lifts, push ups, jumping jacks) don’t involve any exercise equipment at all. Before you get started, make sure you’re in good health with a doctor’s visit. Then, I recommend trying something like the lifetime fitness ladder, which takes those “do it at home” exercises and makes a nice, defined system of exercises to follow out of it, all of which you can do at home in privacy.

31. Do a “Wikipedia walk.” I often burn a good hour doing a “Wikipedia walk” as I investigate a particular topic and find interesting connections to other areas of personal interest. All you have to do is think of a very broad topic you’re interested in - say, philosophy - and read through that entry, following any and all links that are of interest. What I usually do is open up a bunch of new browser tabs from links on that first entry, then read each tab, opening new ones, until I’ve had my fill. It’s a great way to learn the details of any topic, from knitting to the Eastern Orthodox Church.

32. Start a natural collection or sketchbook. All that’s required to start a natural collection - or a notebook that collects observations - is an interest and a willingness to investigate. Like rocks? Start collecting and identifying particular samples. Birds? Make some sketches or take some photographs. There’s no limit to what you can observe and record in the natural world. You can observe people, too, or automobiles - the possibilities are endless. Here are some tips for getting started with a natural collection.

33. Organize your collection(s). Speaking of collections, one wonderful solitary activity is organizing your currently-existing collections. Go through your collection of CDs, DVDs, trading cards, books, political buttons, or whatever item you collect and put them in a reasonable order. Along the way, you’ll find all sorts of little things to do to pique your interest, simply from your personal enjoyment of the things you’ve collected.

34. Learn how to juggle. Juggling is a really enjoyable pastime: it teaches hand-eye coordination and dexterity while simultaneously being quite soothing. It’s also quite simple - you just need three balls to learn how to do it. Here’s an excellent tutorial video on how to juggle.

35. Play a free online game. There are countless sources of excellent online games - try Kongregate and Yahoo! Games, for starters. Lately, I’ve been playing Ticket to Ride: Europe a bit online using the free trial - it’s one of my favorite board games and it’s a blast to play whenever I like.

36. Seek out a solitary place on foot. One activity I particularly enjoyed doing during my college days was exploring seemingly crowded places but searching for nooks and crannies that were completely isolated from the hubbub. I used to find small back rooms of the large university library and just curl up in there and read. I also used to climb the large trees on campus to get up above the crowds below. The search for solitude was enjoyable and finding it was sublime.

37. Start (and maintain) a journal. This is an activity that my wife has recently started and she’s thoroughly enjoying it. Just start on any old spare notebook you have lying around your house. Just jot down the most interesting things you did that day - even if they don’t seem interesting right now. Eventually, you’ll start to build up a nice catalogue of entries and it’ll become quite fun to read earlier writings.

38. Go to a free movie. If you look around a bit, you can often find free movie showings in your community. Start by visiting the libraries available to you - many have open movie nights, where you can go sit in the library auditorium and enjoy a free film. If you live near a university, there’s often a film group there showing a weekly movie as well. Often, other community groups will put on regular film nights as well - just check around.

39. Take up walking, jogging, or running. There are almost no solitary activities that combine physical exertion, rhythm, and peace of mind like sustained walking, jogging, or running, and all you really need to get started is a pair of decent shoes. Define a regular, sensible jogging routine (three times a week for thirty minutes is a good way to get started) and dig in on the paths around you. The key isn’t to kill yourself, but to just exert yourself a little and figure out how to get into a good, healthy rhythm along the way.

40. Take a long, hot bath. Just fill up your bathtub with some nice, warm water, get yourself in there, and kick back. Enjoy the long soak and just let the little worries drift away for a while. To me, this is almost as good as a professional massage but the cost is just right - plus it’s just as convenient as the bathroom down the hall.

41. Rearrange (and thoroughly clean) a room. Sometimes all it really takes to make a place seem fresh and new is a thorough cleaning and a rearrangement of the decorations and furniture. Put some elbow grease to work in your favorite room in your home that’s just a bit tired and see what you can do to make it smell and look fresh again. If it’s a regular place where you spend time, just that little bit of change can make a world’s worth of difference.

42. Write a poem. This is an activity that forces almost everyone to think a bit differently about the world around them, but from that experience can come much wisdom and growth. Try to express whatever you’re feeling in your heart in words, in whatever form seems the most natural and appropriate. Then tease the words around a little - find ones that seem to click with how you feel. The entire process will leave you feeling interesting things - and often feeling deeply fulfilled.

43. Get politically informed. Find out what candidates are going to appear on your ballot in the upcoming election (as well as any ballot initiatives) and find out more about each one of them. Compare the candidates running for the same office and make a rational decision about each campaign. You can do most of this research online today - if you can’t, call the local offices of each political party to find out about local candidates. Doing this will make you an informed voter and likely an influential one, since you can state clear reasons why you’re supporting the candidates you’re supporting and this can often sway others.

44. Take some digital photographs and share them online. If you’re building a natural collection or observing anything interesting at all, take along your digital camera and snap some photographs of it (if you don’t have a digital camera, borrow one). Then, take these images and share them with others on a photo-sharing site like Flickr. Be sure to put in the effort to add detailed notes about each picture so that others may enjoy them as well.

45. Discover new music you might like. There are countless online tools available to you that can help you find new music that matches your tastes. My favorite is Last.fm, which allows you to type in the name of a musical artist you like. Based on that information (and the listening habits of millions of iTunes users), the program will create a radio station of nothing but similar artists, virtually ensuring you’ll find at least something compelling.

46. Create an interesting video and share it on YouTube. All this takes is a digital camera capable of capturing video, some basic video editing software (like the free iMovie for Macs or Windows Movie Maker for PCs), and some creativity. Think of something interesting that you could make a compelling video about, create a tight script for that video, then go around collecting the shots you need. Once you’re done, edit the video into a slick presentation and upload it to YouTube for the world to see.

47. Enter a short story competition. Short stories are a lot of fun to write - in fact, writing them is my secret passion. Whenever I have spare time, I like to seek out short story competitions, write out stories for them, and then … fail to actually enter because I’m too self conscious about my short stories. But I still gain something big from it - the process of writing a short story is a lot of fun.

48. Dig deep into a blog. Got a blog you enjoy reading (like, say, this one)? Go way back into the site’s archives and read some of the older stuff. You’ll often find that the writing has changed drastically since the early days and that you’ve missed out on a ton of interesting and compelling ideas. Look for an “archives” page - for The Simple Dollar, you can start with the chronology.

49. Attend a free concert. Many communities offer free weekly municipal concerts in the park and larger cities often have multiple free concerts each day in various places. Pay attention to the community calendar and other resources and go by yourself to a concert. Live music can be a very compelling and exciting thing - don’t miss out on an opportunity to enjoy it.

50. Watch a sunrise or sunset, from beginning to end.
This really says it all:

That picture depicts sunset over the Grand Canyon in July 2005 when I visited there with my wife. The amazing part of that scene is that you can enjoy much the same beauty anywhere you are, early in the day or late. Just watch the sun rise and take on brightness, or watch her set and shed her colors. Beauty, indeed.

Before my financial turnaround, I subscribed to several expensive hobbies. I loved to golf on the weekends, I played Magic: the Gathering somewhat competitively, I collected DVDs (of certain directors, actors, etc.), and I thought it great to eat out as many meals as possible at high-end restaurants, among others. Each of these hobbies was a massive drain on my bank account, constantly consuming money in huge bites like a cash-starved elephant.

Since then, I’ve given up most of my hobbies and channeled the remainder into paths that are much more financially stable. In order to channel my hobbies into more financially sensible paths, I had to adopt a handful of useful tactics. If you have a hobby that’s a constant money drain, try some of these to see if you can make it more financially sensible.

Tone down your competitiveness
I played Magic: the Gathering in a very competitive environment, constantly attempting to qualify for $25K tournaments and the like. In order to keep up with the other players attempting to do the same, I had to throw quite a bit of money into the hobby at the start, then as I grew sufficiently skilled, I didn’t spend as much on the hobby as I spent on long car trips going to tournaments, hotel rooms, and the like. My competitiveness was in full swing, even if I didn’t have nearly the time to devote to it as others did. I still spent far too many weekends burning money on more cards, tournaments, and so on.

The solution for me was simply toning down my competitiveness. I still play on occasion, but it’s usually just to meet up with friends. I tend to just borrow whatever cards they have extra and play with those, and I don’t travel to tournaments - I just play locally on occasion. This enables me to still get much of the joy and social connection I had during the days when I played heavily, but it doesn’t require me to constantly dump cash down a sinkhole.

Focus on low-end equipment
When I was avidly golfing, there was always a push to have the latest and greatest equipment - massive drivers, well-crafted irons, and balls that flew a mile. It was almost like an arm’s race - who would pull the most impressive weapon out of their bag?

Fortunately, I saw the light here as well. Golfing can be just as much fun with a dirt cheap four iron and a used golf ball as it is with the latest Titleist equipment. Sure, your shot might not fly as far through the air, but that just means you yank out the three iron instead of the four iron. Problem solved - and golf becomes much cheaper to enjoy.

If you have equipment that does the job, stick with that equipment. Don’t worry about blowing money on a barely-better piece of equipment if the old one does the job just fine.

Learn the craftsmanship
Whenever I’d go out to eat at restaurants, I’d simply marvel at the amazing foods put out before me. The amazing breads, the delicious cheeses, the fine beers and wines, the tender entrees - I was always impressed by the amazing quality and craftsmanship.

What I found, though, is that I had much the same joy in my own kitchen preparing my own foods. I got to enjoy the craftsmanship of making foods for myself - the joy of homebrewing, the pleasure of baking my own bread and making my own pasta, and so on. I moved from spending $30 on a restaurant meal to spending $10 in ingredients and a passionate hour in the kitchen creating something amazing for myself. I found that spending an hour making homemade fettuccine was well worth the time invested, as I began to intimately understand the elements of good food that made me love it.

You can apply this to almost anything you’re passionate about, from soaps to clothes. Instead of spending tons of money in the stores or shops on this stuff, channel that passion into learning about the craftsmanship behind the item. You can make almost anything (aside from some electronics) at home with some basic equipment, some time, and some passion. Instead of just enjoying buying what others make, channel that interest into making it yourself.

Understand what you’re actually collecting
I used to collect reams of DVDs - they nearly overwhelmed our old apartment. I’d buy huge piles of DVDs so that I could have all of Johnny Depp’s films on hand, or every one directed by Akira Kurosawa. Thankfully, I got that desire under control, because I realized that I was spending $20 a pop collecting something that I rarely actually looked at after the first experience. It turned out that what I was actually collecting was the experience of a great film with great actors, great scripts, great directors, and great cinematography.

Instead, I made it a point just to watch every Kurosawa film and every film with Depp in it. I’d check them out at the library and enjoy them. Some I’d check out time and time again, and if that happened, I’d usually put them on my Amazon wish list. I also made a concerted effort to purge all of the unwatched stuff from my DVD collection, narrowing it down to stuff I wanted to watch again and again or stuff that I intended to share with my children later on.

Now, I use a number of tools to enjoy movies - the library, trading with friends, and SwapADVD chief among them. I still get that rush of the experience of watching a great movie, and I’m still collecting Johnny Depp films - but now I just collect the experience of watching them.

Hopefully, some of these tactics will help you get some of your own expensive hobbies in line.

My wife and I are both natural collectors. As a young boy, I carefully collected thousands of baseball cards, spending my allowance each week on Topps wax packs. Later, in my teen years, I collected Magic: the Gathering cards with a ferociousness. I come by this naturally - my father has been an avid coin collector, the type who will sift through large jars of pennies looking for rare ones and saving them in individual sleeves. Similarly, my wife has collected books her entire life and has amassed an amazing collection of them, filling multiple shelving units in our basement.

Collections are incredibly enjoyable hobbies to have. When you’re caught in the passionate fire of collecting, you can burn whole days organizing what you have, determining the holes you need to fill, and simply enjoying the items.

The only problem is that most collections cost a lot to get started and have a significant maintenance cost, too. Sports cards require a constant outflow of money for items that might never retain their value. Books? Once they’re bought, the best you can hope for is to sell them used (or trade them) at a huge loss - the same goes for almost any media collection. Most collectibles, like Beanie Babies, fall under the same conclusion - you’re often sinking a lot of value into something with very little financial return, just personal enjoyment.

If you have that collector itch, one approach to solving this problem is to switch your focus towards collecting things that have minimal acquisition cost - or better yet, no cost at all. The best place to start is to look at the nature around you and find the things you find beautiful. Here are some ideas to get you started.

Collecting Nature Samples

The most obvious way to begin a natural collection is to identify items in nature that you can easily collect. Some things to think about if you’re pondering such a collection.

What do you find beautiful? Think about the elements of nature that you genuinely find beautiful. Birds? Trees? Plants? Rocks? Don’t limit your mind to what’s easy and obvious - spend some time thinking about it. For example, I find geodes to be stunningly beautiful, and there’s also a family tradition to them as well - my aunt was one of the most avid geode collectors I’ve ever met, spending most of her spare time in her adult life wandering around in the woods and in creek bottoms finding them. I myself love collecting leaves - as diverse and as colorful as I possibly can find. I take a lot of pleasure in attempting to identify trees based on their leaves.

What is reasonably accessible to you on a regular basis? For example, geode collectors pretty much have to live in the Midwest, as geodes are somewhat common in this area but rare elsewhere. Many collections, such as tree leaf collections, can be started anywhere and expanded upon regularly when the opportunity strikes, but don’t start a collection that you’ll have difficulty expanding near your home.

What doesn’t take up much room? You’ll also want to start a collection that won’t overwhelm your living quarters with clutter. For example, bird feather collections, if done carefully, can be stored in a binder, but collecting tons of large rocks will quickly create a problem (and make moving a nightmare, too). My aunt’s geode collection dominated their front porch, standing on every rail, and at times spilled over onto an adjacent table or two.

Can I get the family involved? If you’ve got a family, find something to collect that everyone can get involved with. Talk to everyone about it, and come up with something that everyone can get involved with. One good idea is to collect rocks of a certain color that match your external decor, bird feathers, or distinctive leaves. This can be a great opportunity to have your entire family get more in touch with nature.

Collecting Natural Observations

Another way to enjoy collecting nature without having to store anything at all is to collect natural observations. If you decide to collect observations, the sky’s the limit - you can basically collect anything. Identify trees and native plants, view constellations, watch birds, identify rocks you find in nature, identify cloud formations - anything you can imagine.

Take careful notes when you observe things. Note where you were when you identified it, the date and time, and as many specifics as you can about the observation. Doing this will help you recall what you observed in the future - a nice collection of observations can be a real treat to go through on a day when you’re itching to go outside but the weather is an obstacle.

Get a good notebook to record your observations. Take notes on what you observed and when you observed it. If you have even minimal artistic skill, try sketching what you see. My wife and I each have sketchbooks - mine is a Moleskine reporter’s sketchbook, which works absolutely great for taking notes and making sketches of all kinds.

Consider a field guide, as well. Another useful tool if you get into natural observation is a field guide for your specific area of interest. For example, if you’re into night sky observations, try the National Audubon Society’s Field Guide to the Night Sky (my wife has that one - it’s stellar) or, if you’re into rock hunting, look into the Field Guide to North American Rocks and Minerals. We own several National Audubon Society guides and have found them all to be excellent.

Nature Photography

Another option, if you have a digital camera, is to augment your natural observations with nature photography. Go out in the world and start taking pictures of the things that interest you - and build a nice collection of natural snapshots.

If you have a digital camera, take lots of shots. A large memory card can hold tons of pictures, so don’t hold off for the “perfect” shot. Start taking images right away. You can always toss the imperfect ones later on.

Record some notes, too. Note anything important about the pictures in your sketchbook for later reference, so that if you go back and look at the pictures, you’ll know what was depicted, where you took it, and when. Write down anything else of note as well.

Share your best nature photography with others. Join Flickr and share your best images. Add information about where the picture was taken and what’s depicted and tag it appropriately so others can easily find the pictures. Even better, allow them to be used widely via a Creative Commons license so that your images can be shared all over the place - you never know where your image might show up.

The natural world is amazingly beautiful, complex, and interesting, and it’s just sitting outside our doors, free to examine and explore. Take advantage of it to fuel your collecting urges and get in touch with the world around you.

Quite often, I admire my cousin and his wife for some of the frugal things they choose to do in their lives. They buy late model used cars and drive them until they need replaced, eat out only on extremely rare occasions, and know cold which generic products are basically the same as the name brands. They’ve replaced almost all their light bulbs with CFLs and have actually disconnected their cable because they don’t use it much.

That’s why I was shocked recently to find out that they’re actually in a frightening debt situation. Why? They take that money that they save from frugal choices (and more) and then spend it on incredibly expensive toys. They have several ATVs, a huge array of hunting equipment, a taste for nice clothes, and their children have virtually everything they ask for.

The end result? Frugality isn’t helping them with their financial situation. They’re already doing it in some avenues of their life, but in other ones, the spending is so overblown that it undoes the buckling down. Often, the argument offered by people in this situation - including my cousin - is that the nice stuff they have is what they work so hard for, but if you ask them what happens if they were to lose their job, a deep look of fear pops up in their eye.

What can you do if you’re in this situation, where your basic needs are actually well below what you’re making, but you find yourself spending everything you bring in - and more? Here are some suggestions for putting yourself in a safer financial situation.

First, don’t give up your expensive hobbies. This might seem like shocking advice, but I’ve found that if you give up something you’re really passionate about, it works about as well as an “all-salad” diet - you do it great for a while, then relapse with crazy splurging.

Look at my cousin’s situation. He spends almost all of his free time with his family doing outdoor activities: riding around on their ATVs, hunting, fishing, and so on. It makes natural sense that he wants to spend his entertainment money on these things - and he should. Life is boring if you don’t have an outlet for your passions.

For me, my hobbies are reading and writing and some video game playing (and a little bit of music). My biggest expense is games for my Wii and DS and occasionally a computer upgrade. While I’m tempted to buy every interesting Wii or DS game I see, I’m pretty careful to not do this.

Instead of spending extra money on hobbies and entertainment, though, set up an automatic savings plan that takes some of the money out of your reach. That way, there’s no money sitting there to tempt you to spend. Take, say, $100 a month out of your checking and into your savings, and don’t touch it until you desperately need it.

You’ll find that your spending adapts to this new available amount. Maybe you’ll move from two new outfits a month to three every two months, or maybe you’ll hold off a few months on your next ATV upgrade. You still get to enjoy your hobbies and have those things that really drive you, but you also get to start putting away money for the future.

What I’ve found for me is that buying one video game, making a very earnest effort to master that game, and then move on to another one is a great way to keep my video game hobby alive with a lot of enjoyment but without much spending. Similarly, I hit the library and PaperBackSwap when I have a desire to read a new book (right now, for instance, I’m reading through most of John Steinbeck’s novels, all of which I could get through PBS or the library).

Over time, slowly increase the amount you’re withdrawing into savings. This works very well in conjunction with discovering new avenues of frugality or increases in salary, or if your interests begin to change.

You may also want to start making extra payments on outstanding debts. Now that our emergency fund is built up well, we have started making extra payments on our student loan debts, and it feels very good to watch them melting away. Once that’s done, we’re going to tackle our home loan with extra payments. This is a good move to make once you have plenty of money socked away to cover any emergency.

Soon, you’ll find yourself in a safer financial situation, and that’s exactly where you want to be.

This post is part of The One Hour Project, in which you can spend just one hour to put your finances in a better place without a big lifestyle change, through frugality or other financial choices.

Most of my friends have huge shelves full of DVDs and CDs that they rarely listen to or look at. Not long ago, I suffered from the same condition - I had this huge array of DVDs that I watched once, shelved away, and didn’t touch for years. In other words, it wasn’t long before they became just something else to dust.

What most people don’t think about is that there is cash just sitting there on those shelves, just waiting to be collected. You might not get a great return on each one, but in just an hour, you can liquidate the collection and put some cash in your pocket - hopefully for the purpose of eliminating some debt or investing in something that will actually generate wealth over time.

First, go through your DVD or CD collection and select a portion of them to liquidate. In the past, I found that choosing a certain percentage to keep is a great tactic to use. Try going through the first time with the goal of keeping 40% of the collection while eliminating 60%. I usually count each “box” as a single DVD for the purposes of this, but you can do it a different way if you like. The goal is to separate the wheat from the chaff - which ones will you potentially watch again and which ones will just sit there on your shelf?

Next, sell them off. For the most part, it’s not worth the additional effort to sell single DVDs on eBay or Amazon auctions, but boxed sets are often worth that extra effort. For the individual DVDs, even though your rate of return isn’t as good, I usually found the best method to be to just take them to a reseller of used DVDs. You might be able to get more per DVD online, but the effort per sale would eat up that gain very quickly (unless you made this into a hobby for a while).

After that, make an effort to enjoy the stuff you kept. If you kept this DVD because you intend to watch it again, watch it again! Go through your DVD collection and watch all of these movies and television shows that you chose to keep around. If you’re thinking, “Nah, I don’t think I want to,” it might be a good time to ask yourself whether you really want to keep any of them at all - you may want to do another round of purging.

The real key here is to use this money to actually pay down some debt or add to an investment. Some people may be tempted to just blow this money - don’t. Find something truly useful to do with it, something that will benefit you over the long haul instead of just sitting on a shelf gathering dust.

One of the most frequent issues that readers write to me about is my thoughts on purchasing a Wii. I mentioned briefly before the five financial lessons that a Wii purchase taught me, but this didn’t seem to sate the questions from readers. So I’m going to take a brief sojourn here and answer all of the questions I’ve received about the Wii. If you have more questions or your own comments, please drop them in the comments.

Where did you buy it?
First of all, Wiis appear to still be very difficult to find. I bought mine at a local Target that just happened to have two of them left after a shipment came in. I have only seen a Wii actually on a shelf in a store twice and I’ve seen an empty shelf many, many times. I paid the typical $249.99 plus tax price, but I had a 10% off your entire purchase card for Target at the time, so I used it then.

How much have you played it?
I bought the Wii just before I moved (around July 1) and between the moving, a death in the family, and many, many relatives coming to visit, I haven’t had as much time to play as I’d like. I have probably averaged about twenty minutes a day, with the actual reality being about an hour every three days. My wife has played a similar amount, but our play has only overlapped in part. Also, many of my visiting family members played as well.

What are the essential purchases you need?
The system comes with Wii Sports (a truly great game for everyone - it’s just amazing), a single remote, and a single nunchuk controller. The remote is the primary controller for the system - the only time that you use the nunchuk controller (it plugs into the remote to make a nunchuk-like controller with a cable connecting the two pieces for two-handed gameplay) is with the boxing part of Wii Sports and with some of the additional games for the Wii that you might buy.

If you expect to primarily play it with one or two players and don’t know what games you might be playing (the situation I was in), I would also buy Wii Play. It’s a collection of nine more simple games (simpler than the Wii Sports ones, but along those lines) that also includes another remote in the box. That ups you to two remotes, which will enable you and your closest friend (in my case, my spouse) to play all of the Wii Sports games and all of the Wii Play games together.

Does Wii Sports actually get you moving around?
Without a doubt, yes. I’ve worked up a sweat many times playing the games, especially the boxing and tennis games on the included Wii Sports.

What’s the best value for the system?
The Wii also lets you download “classic” video games for a varying cost of $5 to $10 a pop (they’re saved on the Wii itself, so you can just keep replaying them as if you had the old cartridges), and I’ll be the first to confess that this has drawn most of my Wii play time - and perhaps most of my wife’s, too, as she has played Super Mario Bros. and Super Mario Bros. 2 extensively. While I’m not sure they would wow the kids, I grew up playing games like Metroid and Super Mario World, and to be able to have them again on a console hooked up to the television is not only steeped in nostalgia, but a ton of fun as well.

If you played video games as a kid, download a few of your old favorites and play through them again on here. You’ll need to buy the Classic Controller, but after that the games cost between $5 and $10 and you keep them permanently. I’ve found that a few haven’t aged all that well (Punch Out comes to mind), but some have just completely drawn me in again. For my gaming dollar, nothing is as worthwhile as downloading an old console game on the Wii and trying to play through it again.

What’s the best game you’ve played?
Wii Sports, without a doubt. It’s an incredibly well-designed game. Even better - it’s in the box, no extra purchase required. Aside from that, I’ve invested the most time beating Super Mario Bros. 2 again (a downloaded game that cost me $5) and also playing the Wii game Mario Strikers Charged (a very strange soccer game given to me as a birthday gift).

Isn’t it a waste of time?
I mean this as honestly as I possibly can: with the exception of watching two television programs to catch appearances by friends and family members, I have not watched television in six weeks. The only time I’m in front of the television is to play a game on the Wii. It helps me unwind, brings up nostalgic feelings, is a lot of fun to play, and I can put it down with ease and go on to other things. Even better, my wife and I both play it quite a bit - together. Plus, it’s the first console I’ve ever owned where other family members have gotten involved with playing - I haven’t seen my oldest brother touch a video game since his days on the Atari, but he was mixing it up playing baseball and bowling.

This isn’t really personal finance advice, but I felt compelled to post this because of the ongoing NCAA men’s basketball tournament and the prevalence of office pools. If you’re not interested, feel free to skip this post; this is merely an extra posting to fill people in on the details of a strategy for filling out your brackets that I use and that doesn’t require any knowledge of college basketball.

I have been doing NCAA tournament office pools for as long as I can remember, and each year I do the same exact thing, time and again. Time and again, I’m near the top of the office pool. The best part about this strategy is that you don’t have to know a single thing about college basketball to do well with it.

So, if you’re in an office pool but know nothing at all about college basketball, here’s what you do.

For the first two rounds, pick nothing but the favorites in every single game. You’ll get the vast majority of your picks right and you also won’t fall flat on your face because you spent your time picking upsets. This means your Sweet Sixteen should be nothing but one, two, three, and four seeds.

For the rest of the tournament, ignore the seeds and pick the team that had the most wins over the last fifteen games of the season. You can get this information at ESPN.com fairly easily by looking at the full season schedules. If you use this strategy in 2007, that means you’ll have Georgetown as your tournament winner, playing Kansas in the title game, and Florida and Ohio State being your other Final Four entrants.

This is exactly how I picked my bracket each of the last five years, and I have been in the top half of the finishers every year, with two years of actually winning the pool. The strategy is this: I just assume that the top seeded schools really are the best ones until they start facing each other, at which point the hottest team will win.

This strategy won’t win any major online bracket-picking challenges, but it will ensure you a good finish in a small pool.

After my recent post on my quest to reduce spending on hobbies, a reader dropped me a line with the following query:

All of my hobbies are really expensive and so I’m trying to find something cheaper to fill my time. Could you write a post listing some interesting free hobbies?

As per request, here are ten great hobbies that are basically free (a few require internet access, but if you’re reading this, you already have that). I personally know someone who is involved in each of these as a hobby and in almost every case they’re quite happy filling hours doing these things.

Head outdoors. If you’re bored, walk out your front door and just start wandering. It doesn’t take much effort at all to simply wander and see what’s interesting out there.

Collect something natural. My aunt spent most of her adult life collecting geodes; an uncle of mine used to collect rocks and seashells to line the shelves of his home. In both cases, the hobby cost nothing but time, and it gave them the opportunity to wander around outside in the fresh air. If you don’t know how or where to look for a particular thing, dig around on the ‘net and you’ll find tons of help. Myself, I love hunting in the woods for mushrooms in the spring, something I plan on posting a photo diary about in April or so.

Start a blog. You can get a free blog at Blogger or WordPress. Just write about whatever interests you (your favorite television show, the books you read, your politics), but stick generally to that topic. If you have a lot of topics you think about, start a few of them. It’s a great way to find people with similar interests, dig deeper into your own interests, and practice your writing skills without the pressure of being judged (much). Even better, you can use a blog to record your growth in one of the other hobbies listed below. In fact, this is exactly how The Simple Dollar got started.

Clean up your area. Is your neighborhood sometimes trashier than you would like it to be? Spend some time walking around collecting trash on the street and making your neighborhood a cleaner place. Quite often, one person doing this on a regular basis will spur others to join you and you can really spruce up a neighborhood. You can also informally adopt a piece of highway and do the same thing.

Join a community group. There are tons of interesting civic groups out there, even in small towns. Start attending city council meetings and asking questions about what’s happening. Attend school board meetings. This is a great way to get started in local politics and start changing things at the neighborhood and town level - remember, all politics is local. If that’s not your cup of tea, look for other civic-minded groups, like the Lion’s Club.

Practice self-improvement. Find areas of yourself that are weak and look for ways to improve them. For example, if you’re weak on public speaking, look for a local Toastmasters group. If you’re weak on your reading skills or don’t know much about a particular topic, start reading more by visiting your local library and checking out simple books. If you’re out of shape, start a simple exercise plan.

Do puzzles. If you like to exercise your brain, try doing the hordes of free puzzles available online. Why ever buy a sudoku book when there’s WebSudoku.com, for example (it’s the only place I ever do sudoku, and I usually do one hard one a week or so). If you like crosswords, hit BestCrosswords.com. These are great ways to stretch your mind a bit and learn new things.

Start a garden. This has a tiny startup cost in seeds, but tending a garden can provide almost endless entertainment for the studious type. This is the preferred hobby of my retired father, who keeps an immaculate garden almost an acre in size.

Volunteer. Look for community organizations that you can volunteer for. Spend some time working in a soup kitchen or at an after-school program. Not only will you feel really good about the use of your time, it will probably change your perspectives on the world a little bit.

Master something interesting. Figure out something simple and interesting and master it. I know one person who is utterly amazing at solving a Rubik’s Cube. She can do it in about fifteen seconds (after examining it) and is working on mastering it blindfolded. It turns out that this is a great party trick. Another friend of mine is incredibly good at playing a guitar, but he can’t read sheet music to save his life; he just toyed with it until he mastered it.

Did none of these sound interesting? Here’s an enormous list of hobbies, most of which are free or nearly free.

The key thing is to find something that gets your juices flowing; if it doesn’t cost anything (or doesn’t cost much), that’s great. If you can produce things that earn money, that’s even better.
