If you ask me where has been the one area where I feel that I've been most frustrated and most stymied it is the fact that the United States of America is the one advanced nation on earth in which we do not have sufficient common-sense, gun-safety laws. Even in the face of repeated mass killings. … And for us not to be able to resolve that issue has been something that is distressing. But it is not something that I intend to stop working on in the remaining 18 months.

Realising that success wasn't going to keep me happy all my life.

Not being a scratch golfer.

That I never found a way to stay in a relationship long term. I always feel trapped.

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.

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.

Nobody has ever accused me of being a superior communicator. If I could have conveyed to the American people the concerns I had, and my heartbeat, a little more clearly, maybe I would not be unemployed and retired. And I might not be this happy, either. I learned a lot from Ronald Reagan about communication. Never got to be in his league in terms of it, but he could say something and the American people might not agree with the issue, but they could empathize with him.

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.

Abraham Lincoln truly inspired me. It wasn't just the freeing of the slaves, he kept the Union together. Some people even forget that today. What I think inspired me was the fact that in spite of being the president of the United States he retained a certain down-to-earth quality. He never got to be a big shot, and he cared about people.

It’s family, and it’s faith, and it’s friends, and it’s not the glamour of the Presidency, or the wonder of going to receive the Nobel Prize. All those are important, of course. But maybe it’s just that I’m 71 years old now. It’s family, and it’s faith, and it’s friends.
