As you will eventually see, the older you get the less anybody in the world gives a crap about you. Right now you are self centered. One day you will not have your parents to tell you what to do and you will have to make your own way in life. If you had poor grades

What you mean by decent is perhaps, I should pass my classes, or I should be collegebound? Actually what I am trying to ask is if there I can get a college level education in music without taking other non-music-related courses.

Either way have a weak grasp on your wisdom and that can only grow. I'll need someone to give a crap in order to make enough money to eat.
