Action is the fundamental key to success.

When German soldiers used to come to my studio and look at my pictures of Guernica, they'd ask 'Did you do this?'. And I'd say, 'No, you did.'

If you are a genius and unsuccessful, everybody treats you as if you were a genius, but when you come to be successful, when you commence to earn money, when you are really successful, then your family and everybody no longer treats you like a genius, they treat you like a man who has become successful.

We have learned nothing.

For a long time I limited myself to one colour - as a form of discipline.

Only put off until tomorrow what you are willing to die having left undone.

I try to paint what I have found and not what I look for. In art, intentions are of little importance.
