We all know that iTunes Store has huge libraries full of songs, movies, TV shows, and audio books that you can buy. But there’s also a special section mysteriously named iTunes U (I believe the U stands for university). This part of the store, however, can be freely used, meaning that you don’t have to pay anything for the downloads you get from there. iTunes U opened in 2007, and it houses over 75,000 freely downloadable files related to courses taught at institutions such as Stanford, Cambridge, and MIT.

You can gather a tremendous amount of knowledge from the Internet. When I first got interested in kung fu, the first thing I did was get online and research the tens of different styles taught in the West. I learned a lot by perusing numerous websites dedicated to Chinese martial arts. But what really made the difference and taught me the most were online forums. (If you want to know which one, it was Kung Fu Magazine’s Online Forum.)
