"In the beginning, the energy involved to create came from my reaction to the work of other artists. The force behind this was aggression. The art that I saw was great, but I had to reject it, because I could not continue in the same direction. So I had to do something entirely different. It had to be so different, so extreme, that those who loved pop art, for instance, hated me. And this was my strength. Later, it again worked in a biological manner. But in no way was it just my reactions against things."
