Hobbies?
Oh wow, thats humiliating...
My hobbies are basically 99% music, reading about music theory, becoming proficient on as many instruments as I can, composing, arranging, and I make a hobby out of trying to challenge and improve my tastes by listening as widely as I can... it sounds a little sad, and I don't do a whole lot else, but I'm loving it.
I was planning on becoming a concert pianist but 9 months ago I got RSI and busted up my index fingers real bad (hasn't gone away yet, and doctors say I wont be able to play again) so I widened my hobbies a little... Now i read up on politics and history as well as classic literature, and ride my bike, have a girlfriend, etc.
