In one gallery they actually had a notice which said No Sketching. How obnoxious! I said, How do you think these things got on the walls if there was no sketching?

All painting, no matter what you are painting, is abstract in that it's got to be organized.

It's all one to me: opera, painting, drawing, faxes.

You must plan to be spontaneous.

If you see the world as beautiful, thrilling and mysterious, as I think I do, then you feel quite alive.

As you get older, it gets a bit harder to keep the spontaneity in you, but I work at it.

In fact, most artists want to make things a bit more difficult for themselves as they go along, to challenge themselves.
