The artist should have a powerful will. He should be powerfully possessed by one idea

Do whatever you do intensely. The artist is the man who leaves the crowd and goes pioneering. With him there is an idea which is his life.

Personal experimentation is revealing, and once you get into it, immensely engaging.

An artist must first of all respond to his subject, he must be filled with emotion toward that subject and then he must make his technique so sincere, so translucent that it may be forgotten, the value of the subject shining through it.

Paint like a fiend when the idea possesses you.

Many receive a criticism and think it is fine; think they got their money's worth; think well of the teacher for it, and then go on with their work just the same as before. That is the reason much of the wisdom of Plato is still locked up in the pages of Plato.

Don't stop to paint the material, but push on to give the spirit.
