"Painting doesn't have a function, not in the way that music or film does... I mean, you can dance to music. Music can be used for a soundtrack, so it has a function in that sense, beyond itself. But painting doesn't... But I do believe that painting has a purpose."

I think everybody starts out by seeing a few works of art and wanting to do something like them. You want to understand what you see, what is there, and you try to make a picture out of it. Later you realize that you can't represent reality at all - that what you make represents nothing but itself, and therefore is itself reality.
