Andrew Loomis said this quote

One’s skill is never complete, one’s knowledge is forever lacking, one’s taste is invariably altered, one’s opinion ever subject to controversy. There is a complete and constant urge towards improvement.

~ Andrew Loomis

As a student I thought there was a formula of some kind that I would get hold of somewhere, and thereby become and artist. There is a formula, but it has not been in books. It is really plain old courage, standing on one's own feet, and forever seeking enlightenment; courage to develop your way, but learning from the other fellow; experimentation with your own ideas, observing for yourself, a rigid discipline of doing over that which you can improve.

~ Andrew Loomis

I have never found a book that stressed the importance of myself as a caretaker of my ability, of staying healthy mentally and physically, or that gave me an inkling that my courage might be strained to the utmost.

~ Andrew Loomis

No knack of drawing heads can compete with sound knowledge.
