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.

At the beginning, I thought the best Islamic work was in Spain - the mosque in Cordoba, the Alhambra in Granada. But as I learned more, my ideas shifted. I traveled to Egypt, and to the Middle East many times.I found the most wonderful examples of Islamic work in Cairo, it turns out. I'd visited mosques there before, but I didn't see them with the same eye as I did this time. They truly said something to me about Islamic architecture.
