Norman Foster, Baron Foster of Thames Bank

"Part of the art of being an architect is to be a good listener. But I also believe in always providing strong leadership. Something that is designed by committee, in the end, tends to be compromised."

"[Makes a good architect] an open mind, energy, an appetite for hard work, a willingness to explore new solutions and push boundaries. A sense of humor is also helpful."

"The most amazing lesson in aerodynamics I ever had was the day I climbed a thermal in a glider at the same time as an eagle. I witnessed, close up, effortlessness and lightness combined with strength, precision and determination."

"I'm amazed to be here still and doing all this. But then I look at Oscar Niemeyer in Rio, who was a hero of mine when I was a student at Manchester. Oscar's still busy at work at 102, so there's hope. In any case, I just wouldn't know how to stop."

"I like to find things from unexpected sources. I tend to move between turtlenecks and shirts and ties. I don't really have a uniform in the sense that some people might."

"[A man every day should do] probably self-assess. Do I do it religiously? Not consciously, but I like to think that in one form or another I do question, yes. I would be being pretentious and untruthful if I said that I devote a bit of time just for introspection and consciously do that, but in one form or another I suspect I do. And if I don't, I think it would be a good thing to do anyway."
