Unfortunately, in the case of Iraq, I believe we could have done that through an inspection process. I was calling for a few months more to complete our work. We hadn’t seen indications of weapons of mass destruction. We hadn’t seen indications of nuclear weapons. ... Unfortunately, it didn’t work that way. There was faulty intelligence. There were lots of other considerations that made a decision to go to war tempting, to get rid of Saddam Hussein.

In fact, what I usually say to people, “Probably some of the most successful scientists are the ones that know how to deal with failure well.” Because it’s easy to feel good when you succeed. That’s an easy thing. But you’re probably going to fail in science a lot more than you succeed, so you really have to learn how to deal with it and not let it beat you.

The Godfather was a very unappreciated movie when we were making it. They were very unhappy with it. They didn't like the cast. They didn't like the way I was shooting it. I was always on the verge of getting fired. So it was an extremely nightmarish experience. I had two little kids, and the third one was born during that. We lived in a little apartment, and I was basically frightened that they didn't like it. They had as much as said that, so when it was all over I wasn't at all confident that it was going to be successful, and that I'd ever get another job.

As hard as it's been to come to this decision, I am at peace with it. I have no regrets. I was not supposed to be here in the first place, remember? Not many people believed in my talent and my abilities, yet I found a way to persevere, to prove them (and sometimes myself!) wrong.

My tendency to skip meals.

When I was growing up I wanted to be a minister. I wanted to preach.

More than anything else, I had to combat the barriers, and we tore down those barriers. I just had to set a sail against the wind, those strong winds, to end segregation and racial discrimination, but somehow, in some way, I didn’t let those barriers keep me down.

Barack Obama, because he believed he could be president of the United States, and he succeeded. He was kind, and he tried to set a high standard of leadership.

Jim Lawson. Jim Lawson was an unbelievable human being. Born in Ohio. He was a pacifist. He studied Gandhi. He was part of the Methodist Student Movement. He lived in India. He became an organizer for FOR, the Fellowship of Reconciliation.

I don't want to die. I don't think I'm going to die…but we all have to die. Since I do, I hope I live on in the hearts and minds of people.
