There is stuff I would have liked to have done. But there are no sour grapes.

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.

China is building cities for a 20 to 40 percent increase in population. India is quickly growing. The carbon footprints of that and other development around the world are overwhelming.

When people condemn me for designing iconic buildings in cities and not having an idea what a city is, they haven't done their homework. I started in urban design and city planning. It's just that when I got out of school there wasn't much of a market for that. There still isn't.

Your best work is your expression of yourself.

My buildings are all on budget.

The whole can be greater than the sum of it's parts, that we all have something to put in the pie to make it better, and that the collaborative interaction works.
