I'm very proud of the fact that, in spite of everything, the core mandate in terms of the protection of civilians is really flying very high everywhere in the mission. Everywhere. And I'm very hopeful with the young people of DRC and the women.

Obviously having my family and being able to hold my kids a month ago with that Super Bowl trophy was one that you'll always remember.

I don’t regret having done it at all. I think everything that I went through was worth it. I am very proud. But I would not do it again.

A man does not get to write his own epitaph. But if I were to write mine it would say the following: He loved his family, and he loved his troops, and they loved him — period.

One in particular, Mrs. Gordon. I hated her. I took AP English. The AP courses were just starting in the ’50s. And you could take a maximum of two. I took Chemistry and AP English. Today, the kids come into Duke, they have ten, 12, 15 AP courses. They start taking AP courses in their first year of high school. It’s absolutely amazing. Mrs. Gordon taught AP English. And she took a disliking to me for some reason early on, and she didn’t like the way I wrote, so she gave me very bad grades on all my essays. She pounded into me about how to write clear, effective, succinct English. And I learned those lessons well. But what I remember — and I pay her a tremendous tribute for that because there’s no more important skill, certainly for a scientist, but really for almost any profession, than to be able to express yourself clearly and succinctly. And I think she really taught me that.

I often repeat to them something that — not my mentor, but a senior scientist at the NIH — said to me once. We were having lunch together. I was despondent, despondent because nothing had worked. I had been there a year. And this guy said to me, “Look,” he said, “do you know the difference, Bob, between an average scientist and a world class scientist?” I said no. He said, “Here’s what it is.” He said, “For the average scientist, maybe one percent of their experiments work. But for the world class guy, the world beater, it could be as high as one-and-a-half or two percent.” And then that really stuck with me because it’s really true.
