Spending money on art has always been frowned upon in this country - even earlier, when my and others' paintings cost almost nothing. Something is always more important. The people in charge are always peddling reasons that others seem to accept. Those who don't drink and aren't crazy, or who don't attract attention with how they behave in public, aren't noticed in art.

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.

I did not always trust my teachers, because I found them too weak. I was looking for something that could take me in a new direction, for things that I could admire. And because it was so hard to find this, I became a sort of outsider. That's why I began to identify with the insane, "outsider" artists.

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.

There's a market for art, and things are indeed going swimmingly, especially for German artists. But everything takes place in America and in London, where there are quite a few wealthy, engaged people. What motivates them to buy art is a different question, but they do.

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 am not a representative of anything. When art historians or critics or the public put somebody in a drawer like this, it has a tranquilizing, paralyzing effect. Artists are individuals. They have ideas, and the conventions for one's self as an individual are not for a group. There are always those who follow the group, but they belong in the margins. I refuse to be placed within, or added to, one particular school.
