The best calculation is the absence of calculation. Once you have attained a certain level of recognition, others generally figure that when you do something, it's for an intelligent reason. So it's really foolish to plot out your movements too carefully in advance. You're better off acting capriciously.

If you're stuck in a painting, then stop and draw something else. Draw a flower and put your love into that flower. Then your powers will come back again.

I who have been involved with all styles of painting can assure you that the only things that fluctuate are the waves of fashion which carry the snobs and speculators; the number of true connoisseurs remains more or less the same.

Whatever the source of emotion that drives me to create, I want to give it a form which has some connection with the visible world, even if it is only to wage war on that world....I want my paintings to be able to defend themselves to resist the invader, just as though there were razor blades on all surfaces so no one could touch them without cutting his hands.

The people who make art their business are mostly imposters.

People are always asking me to sign my old canvases. It's ridiculous!

Painting is a blind man's profession. He paints not what he sees, but what he feels, what he tells himself about what he has seen.
