My ability to stress myself out.

Laziness. After 30 years of being a disciplined athlete with an intensely tight schedule, I still can’t forgive myself for letting things slide.

My default will always be to go for the worst-case scenario and that is something that I am unlearning.

Outside my very close-knit group of friends, socially I’m terrible.

If I were to give advice to young people, high-achieving young people for example, I'd have to say, don't neglect your family. Politics is important, sitting at the head table is glamorous. Traveling around the world, trying to do something for world peace was wonderful. But family and friends and faith are what really matter in life. And I know that. I see it so clearly now. And so, as they climb the ladder of achievement, I'd simply say, remember what Barbara Bush told those girls at Wellesley: "What happens in your house is more important than what happens in the White House." And it's true. It's so 100 percent true.

This may sound like a cliché, but I’ll put it this way. The proudest thing in my life is that my children came home. The proudest moment of my presidency, domestically, was when I signed a piece of civil rights legislation known as the ADA, doing something for the disabled. A massive piece of civil rights legislation that put disabled people, 50 million of them, into the mainstream, or at least removed legal obstacles to their being in the mainstream.

One of the historians here in Williamsburg talked about War and Peace. I had to read that in school. It was an inspiring, lengthy treatise. I read it twice. It taught me a lot about life. There was a marvelous book by Salinger called Catcher in the Rye. There was a book about discrimination called Gentleman's Agreement. These books I think helped shape my life. But to be honest with you, not one book stands out as the defining book for me.

I don't want to be called a senior citizen, I feel like a spring colt. I don't want to be called a has-been, because there's things I want to do in life. But, I've been there and I'd say, "Don't let the bastards get you down." And they don't anymore, I don't talk to them anymore, so they don't get me down. I've got my family, and I've got so many blessings that I don't think I've earned, that I'm a very happy man.

When I lost a race for the United States Senate, I thought the world was going to end for me politically, and 18 years later I was elected President of the United States. The biggest disappointment was that I wasn't able to communicate properly to the American people — with the proper conviction and the proper ability — where the country really stood. The pessimists, the naysayers, the change-wanters overwhelmed me, and I wasn't good enough. I wasn't articulate enough to have the country understand that we weren't in a recession, that we were in a rather booming economy in the last half of my presidency. That was a personal shortcoming, a failure on my path.

If you really want to make a difference, whether it’s in helping other people, or whether it’s in fighting for your country, or whether it’s in the political arena, or journalism, or physics, you’ve got to persevere. You’ve got to understand that there are going to be some enormous bumps in the road.
