Keeping my children’s feet on the ground. It’s challenging as you become wealthier and wealthier in life, and you see how money very often — third or fourth generation — destroys people. Their inability to appreciate it, understand it, not abuse it. I think I’ve equipped my children well.

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.

I am the only person who has four golds and one bronze in the Olympic Winter Games in Korea. The record will be broken by someone someday, but I think, I've done what I loved and had a pretty good and successful life as an athlete.

That’s easy, my trainees. In my field, receptor biology, the field is dominated by people that I trained. Kobilka is one example. I would say I have, for years — in all due modesty — I led the field. I passed that mantle to Kobilka. He has the newest technologies and this and that. But he’s just the limit case. There are dozens and dozens of people who trained with me that, if you go to any meeting on receptor biology and you look at the program, I don’t know, 30 to 40 percent of all the speakers will have either trained with me or trained with people who trained with me. They’re in the lineage. So that’s what I’m most proud of.

My wife, my children, my friends, myself. I’m my own strongest critic. I am much tougher on myself than anybody I know, consistently.
