The one thing that John Kennedy did, above all else, was to energize young people to feel that they wanted to give something to their country. I just hope, for young people of this generation, that they'll experience that feeling once again, that by working on large goals, they can do something more than their own individual ambition.

The White House is such an extraordinary, simple, beautiful place. It's an extraordinary piece of our history, because it is the one thing that binds our country together. We don't have a king obviously, but we have this president, and the fact that almost all of them have lived in the same place, and so much history took place in those rooms. You can't help but feel awe-inspired by being there.

If your ambition comes at the price of an unbalanced life, that there's nothing else that gives you comfort but success, it's not worth it.

If you interview five people about the same incident, and you see five different points of view, it makes you know what makes history so complicated. Something doesn't just occur. It's not like a scientific event. It's a human event. So the dimensions of it will be seen differently by different people.

(from John Hay's diary) “The President never appeared to better advantage in the world,” Hay proudly noted in his diary. “Though He knows how immense is the danger to himself from the unreasoning anger of that committee, he never cringed to them for an instant. He stood where he thought he was right and crushed them with his candid logic.

I am a historian. With the exception of being a wife and mother, it is who I am. And there is nothing I take more seriously.

There is a sense of feeling larger than your own life when you're in some common mission together. You have to hope it's not going to take a war to bring that back to America again. I think another time when it seemed to be here was in the early 1960s.
