If you know where to look, you can find a lot of great free stuff online. Not just goodies like ice cream and postcards (although those are nice), but stuff like classes from MIT and trial memberships at gyms–things that are a little more enriching.

Here are some of the ones to check out:

MIT Classes
The Massachusetts Institute of Technology is one of the best universities in the world, and it offers a lot of course material online for free. You don’t get a degree, but you will learn. A lot. ocw.mit.edu.

iTunes U
Got iTunes? Then you have a portable university at your fingertips. Many major universities–Stanford, Cornell, Oxford, Texas A&M–offer free educational podcasts on Apple’s iTunes Store. They cover a wide variety of subjects, from evolution to neuroscience to classical guitar. Just download and push play.

Start A Business
You might not think this is the best time to start a new business. But if you have an idea, the U.S. Government’s Small Business Administration can help you make it a reality. The organization offers classes on writing a business plan, registering your company and how to manage business taxes. Learn more at sba.gov.

Museums
North Texas has some truly world-class museums. Some, like the Kimbell and the Carter in Fort Worth, offer free admission to their permanent collections. You usually have to pay for the special exhibitions, but their permanent collections are very impressive. And who couldn’t use a little more culture in their lives?

Get Fit
Many health clubs have free introductory memberships. The goal is to get you hooked on their facility so you buy a full membership eventually. But some of these teaser memberships can last as long as two weeks.
