We have always created - music, literature, art, dance. The art around us - or lack of it - may be a measure of how we're doing as individuals and as a civilization, so maybe we should be worried.

I think you've got to accept that certain things are in process that you can't change, that you can't overwhelm. The chaos of our cities, the randomness of our lives, the unpredictability of where you're going to be in ten years from now - all of those things are weighing on us, and yet there is a certain glimmer of control. If you act a certain way, and talk a certain way, you're going to draw certain forces to you.

People live and work in uninspiring environments, but look inside those rooms. Look at the painted walls and the decorations. People rebel even in the most controlled office environment in which they're not allowed to do anything. You see the little bulletin board in front of a person's desk with their photos, clippings, cartoons and whatever else.

I work from the inside out.

Most of what's around us is banal. We live with it. We accept it as inevitable.
