When I have to think about it, I know the picture is wrong. And sizing is a form of thinking and coloring is too. My instinct about painting says, 'If you don't think about it, it's right'. As soon as you have to decide and choose, it's wrong. And the more you decide about, the more wrong it gets. Some people, they paint abstract, so they sit there thinking about it because their thinking makes them feel they're doing something. But my thinking never makes me feel I'm doing anything.
