Taught myself to program over 6 years ago. I've learned low level and high level languages, algorithms, data structures, how to make websites and mobile applications, etc, etc. While I may have wished for an instructor at parts (specifically when my computer refused to run certain pieces of software, or when I accidentally wiped my entire hard drive while trying to install linux) in retrospect, I don't think I would choose to do it any other way.

Then again, I prefer learning from reading a book than from being taught. Everyone is different. It must be amazing to have someone guide you and check up on you once in a while though.
