The Internet, and specifically YouTube, is a great place to learn how to do almost anything.
A couple of years ago I discovered Howcast. Howcast used to be an iPhone app but now exists as a YouTube channel.
Howcast produces thousands of online ‘how-to’ videos that are approximately 2 minutes in length. Howcast is an excellent source for people who want a quick video on how to do something. Alternatively, if you only have two minutes, Howcast is a great way to spend your time learning something.
Some examples of great Howcast vidoes:

By taking advantage of what the Internet has to offer, the possibilities of things to learn are limitless.
