To teach one's self is to be forced to learn twice.
Study depends on the goodwill of the student, a quality that cannot be secured by compulsion.
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.
