I have always believed that every great city in history needs a vibrant center.

You can have great teachers, but if you don't have a good principal, you won't have a good school.

Los Angeles is such a great meritocracy. Where can someone with my background - don't have the right family background, the right religion, the right provenance or whatever you want to call it - I come here and I'm accepted. The city's been good to me. And I want to give back.

One great building does not make a great city.

Dallas is a great city, and it's worth fighting for.

I don't see myself as a great discoverer of artists, like Charles Saatchi.
