People live and work in uninspiring environments, but look inside those rooms. Look at the painted walls and the decorations. People rebel even in the most controlled office environment in which they're not allowed to do anything. You see the little bulletin board in front of a person's desk with their photos, clippings, cartoons and whatever else.

You've got to bumble forward into the unknown.

Cardboard is another material that's ubiquitous and everybody hates, yet when I made furniture with it everybody loved it.

My buildings are all on budget.

The back of Saint Peter's is one of the finest pieces of architecture I've ever seen.

When I start my class I ask the students to write their signatures on pieces of paper and put them on a table. I have them look at them, and I point out, "They're all different, aren't they? That's you, that's you, that's you, that's you."

You never build the perfect building. Only Allah is perfect. Life is such. You make decisions on conclusions, then some guy invents something else and the world changes. That's comforting. There's no one way to use museums, no one way to do art. That also means there is no one way to build museums.
