As I was starting my academic career, it was almost considered to be a negative signal to your career to get involved in politics ... But to me that was a sign you were doing something useful.

I realized very early that non-egality would work better in the parts of the world I wanted to inhabit. What do I mean by non-egality? I mean John Wooden, when he was the number one basketball coach in the world. He just said to the bottom five players, “You don't get to play. You're sparring partners.” The top seven did all the playing.

I’ve been mortally opposed to the so-called life-and-death committees that were instituted. When there were many more patients that needed to be dialyzed, and not enough artificial kidneys available, you had the institution of the life-and-death committees. ... Depending on the answer to these questions, he could be dialyzed. Otherwise, he could go to hell. I’ve been mortally opposed to that. When I set up a dialysis center here with a grant from some government agency, I was forced to put in a life-and-death committee, but it never met.

Our young should prepare to seek their fortunes in this golden age. It is silly to moan that properties and cars are going out of their reach. They will never be out of reach of those who seize their opportunities. Of course those on profit sharing schemes and stock options will do better than those on salaries. But even those on salaries will have their salaries double in the next 10 years of high growth. The big winners will be those who find a vein of gold and dig it out. But you have to work to find it and dig it out. Those who bemuse and befuddle themselves into believing the great opportunities are already behind them will regret it when they see their more discerning and perceptive contemporaries prosper.

I have never liked the word retirement. It doesn't feel like a modern word to me. I've been thinking of this as a transition, but I want to be sensitive about how I use that word, which means something very specific and important to a community of people. Maybe the best word to describe what I'm up to is evolution. I'm here to tell you that I'm evolving away from tennis, toward other things that are important to me.

Taking time every day to read the Bible.

Any lost match is, of course, disappointing, but every loss is a lesson to be learned.

My mom and dad. They always encouraged me to keep spiritual things first.

But these days, if I have to choose between building my tennis résumé and building my family, I choose the latter.

I wouldn’t change anything about myself. If you asked me 20 years ago, I probably would have had a long list. But I’ve learned to appreciate and love who I am.
