I think that generally music should be a positive thing, I like Bob Marley's attitude: he said that his goal in life was to single handedly fight all the evil in the world with nothing but music, and when he went to a place he didn't go to play, he went to conquer.
My grandfather gave me my first guitar, an old acoustic with palm trees and dancing girls painted on it.
I may sometimes be willing to teach for nothing, but if paid at all, I shall never do a man's work for less than a man's pay.
