When I work, I work very hard. When I don't work, I have to do something where my endeavor can totally take me off what I do professionally, like sailing. It takes all your attention.

Working is actually a pleasure. It's just very time-consuming. It's a way of life. I find that I can work when I travel and work when I run. There is nothing like, on a rainy day, to work.

It's my goal to make a building as immaterial as possible. Architecture is a very material thing. It takes a lot of resources, so why not eliminate what you don't need as long as you're able to achieve the same result?

Creativity has more to do with the elimination of the inessential than with inventing something new.

For me, drawing generates thinking and vice versa.

You'd never think of taking a cab if you had to walk a mile down Chicago's Michigan Avenue. But in a bad city you take a cab just to go around the corner.
