You can't love what you don't know much about. You can't convince, stimulate, hold the attention, teach, if you don't know what you're talking about.

We still dislike hypocrites. It's a very American characteristic. We still like people who have ideas and who are willing to stand up for what they believe in. We're very forgiving of failures and very willing to give people a second and third chance if they mean to do better and are sorry for what they've done.

My wife, the star I steer by.

Since September 11, it seems to me that never in our lifetime, except possibly in the early stages of World War II, has it been clearer that we have as a source of strength, a source of direction, a source of inspiration - our story.

My shorthand answer is that I try to write the kind of book that I would like to read. If I can make it clear and interesting and compelling to me, then I hope maybe it will be for the reader.

I think that a good education ought to be in part the idea that ease and joy are not synonymous. Some of the most fulfilling pleasures of life are to be found in work - found in work you love to do, work you want to do, work that makes you want to get out of bed in the morning.

My strong feeling is that we must learn more about how we learn. I'm convinced that we learn by struggling to find the solution to a problem on our own with some guidance, but getting in and getting our hands dirty and working it.
