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.

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 started collecting my artist friends, artists like myself who nobody had yet noticed. In everything, all I am collecting, so to speak, are my friends - artist friends.

I do not have a philosophy about retrospectives. Of course, I cannot change what I have done. What I am doing today, this I can change, in view of whatever I have done before. My retrospectives are like a series of ghosts.

A painter doesn't need any talent. In fact, it's better not to have it.

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.
