Being a good artist isn’t altogether different from being a good writer, physicist, athlete, doctor, lawyer, panther, or any other profession/wild animal. There is a back catalog of preexisting rules, guidelines, techniques, history, and even ethics and culture – all of which need to be studied and applied practically through relentless practice.
Art, in its most technical and creative forms – isn’t something that belongs to these special gifted snowflakes – it’s for anyone. How relatively good or knowledgable you get at it, is just a simple matter of much you’re willing to let it consume and permeate every fiber of your being. That willingness to put your entirety into something to the point of obsession, regardless of what it is — that … that’s something that might not be in everyone.
