Btw, don't drop highschool in order to play guitar more, because:

a) 5-6 hours a day is already more than enough, and
b) you need something to fall back on, what happens if you get tendonitis or tunnel carpel?

sorry I'm still not sure how to make other posts' quotes all fancy like..... but there is nothing to fall back on, ever. Music is all that is and all I will ever do. If I got tunnel carpel or tendonitis I would spend the rest of my days treating it in every way possible, a positive attitude can heal any wound. Tony Iommi lost his fingertips but that didn't stop him from doing what he loved! With the will to play I can play. ( this is not an attack on you at all, you believe you are doing a right and helping a kid to stay in school, I salute you .)
by the way, I withdraw my previous statement, "smoking can take it all away." because tendonitis cannot take it all away, my bad.
