Study depends on the goodwill of the student, a quality that cannot be secured by compulsion.
To teach one's self is to be forced to learn twice.
Few have been taught to any purpose who have not been their own teachers.
I have spent my whole life educating myself.
Actually I've never had formal training, I was lucky enough to continue working most of my career and aside from sitting in on a couple of classes, here and there, I basically just use my own instincts.
Studying music, everyone sort of has their own style - it's not like everyone's going for the same part.
I learned from my parents the idea that, if you are devoted enough and you want to study something enough, you can really teach yourself anything.
I study for myself, my own games and others.
Do your own homework. I can't overstate the importance of this.
