You should finish school now that you are so close. It took me 7 years to get a B.A. on account of my goofing off for too long, but I always wanted to be a professional producer but have not managed that yet, I dont know why but I do know that you need to put all your energy into the one thing you really want to do, dont wait, just do it NOW, or youll end up like me with literally 1000+ songs written and you don't know what to do with them.
