I started with piano because my older sister took it (and went on to be a piano major), but after having a few completely awful teachers I stopped and hated most music for about a year.
Then something horrible happened, and my step dad had just given me a guitar, and I didn't want to think much, so I just picked it up, (and since I already had some theory) went online and taught myself.
Then my step dad got a dulcimer and I learned it.
Then I just wanted to learn more and took my friend/guitar 'mentor's' bass on a regular basis.
And then recently I got electric drums.
So I guess my not wanting to think and my step dad got me into music.
