You don't paint the way someone, by observing his life, thinks you have to paint, you paint the way you have to in order to give. That's life itself, and someone will look and say it is the product of knowing, but it has nothing to do with knowing, it has to do with giving. The question about knowing will naturally be wrong. When you've finished giving, the look surprises you as anyone else. Some painters talking about painting are like a lot of kids dancing at a prom. An hour later you are too shy to get out on the floor.
