I quit school to go to berklee college of music- high school was interfering with my guitar practice. If I got in 6 hours it was a bad day, 9 hours was a good day. Then I failed out of Berklee because I wasn't interested in learning jazz. I was a young punk with a mohawk and my brother had just passed away- what else could I do but exactly what I want?
16 isn't too young to know your career path. Its when you're at your most bull-headed and idealistic. We do what we can.
