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.

Great artists need great clients.

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.

François Mitterrand was a student of architecture, he had done a lot of research before he called me. He said, "You did something special at the National Gallery of Art in Washington - you brought the new and the old together." But John Russell Pope finished the West Building in 1941, so when the East Building opened it was only about 40 years old. But the Louvre is 800 years old! A much bigger design challenge.

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.

You cannot defend your design without knowing what you're designing for.

Let's do it right. This is for the ages.
