What counts most is finding new ways to get the world down in paint on my own terms.

No one who looks at my paintings can see whether a painting is upside down or not anymore. I've made or developed so many image models that some people have given up trying to keep track of me. But others have only one or two ways of doing things and are successful with that.

I remember that Michael Werner told me about a famous collector, and Michael set up an appointment for us to meet. This man looked around the room and at my pictures. Then he said, "Young man, why are you doing these horrible things? Look out the window. There are nice girls out there. It's springtime. Look at how beautiful the world can be. You'll ruin your health by smoking so much and doing such tortured things."

As a human being, I am a citizen, but as an artist, I am asocial.

I've painted, but I've also done graphics since as long as I can remember. So even people with little to spend could afford it. But even the graphic works are only bought by those who buy the big, expensive paintings. I think that's troublesome.

I don't like things that can be reproduced. Wood isn't important in itself but rather in the fact that objects made in it are unique, simple, unpretentious.

I don't paint over my paintings with black paint. I paint black paintings. It isn't because I'm sad, just as I didn't paint red paintings yesterday because I was happy. Nor will I paint yellow paintings tomorrow because I'm jealous.
