My projects have typically taken a long time to complete. Buildings might take on average about five to seven years to finish, but in my case it's been longer, because the projects I have accepted within the past 15 years have been mostly government projects, and those involve some politics and funding issues, and approvals and so forth. So they're slower.

I believe that architecture is a pragmatic art. To become art it must be built on a foundation of necessity.

On a daily basis, my home life is very simple. I spend about 2 hours every morning reading the newspaper. As my two assistants will tell you, I don't come to work in the mornings, for two reasons. First, I want to be informed - that means I go through The New York Times every day, and then I watch some news on television. The second is, mornings are the best time to communicate with my clients abroad.

I cannot work and listen to Wagner at the same time, nor Mahler, nor Beethoven's late quartets. I enjoy listening to Chopin's piano music when I work.

I was born in Suzhou, a city not very far from Shanghai. It's a very interesting town - there is a long artist's tradition there, especially during the Ming and Ching dynasties, which produced many, many scholars and painters and so forth. That's where my family lived for 600, 700 years.

Great artists need great clients.

I travel to the Middle East, I travel to China, I travel to Europe. It's all very rewarding - the only problem is the travel is getting more and more difficult for me now. Ten years ago I would have enjoyed it a lot more.
