If you play an instrument, which is it?
vabmit: I taught myself acoustic guitar.  First, I learned from books and websites. Then when YouTube came out, I found a lot of very good "How to Play Song X" videos on it.  I really enjoyed learning to play. Spending 5-10 hours a week away from my computer, and not looking at a screen for most of that time, significantly boosted my productivity and improved my morale.  I was pretty burned out and looking for something to do besides computer work, and reading about computers, when I started picking it up.  I haven't played in a few years, though.  As I got older, I kinda lost interest in music (both listening to and playing).
