These tics do bother me. Could I play a match without them? Yes, without some of them. I don't have to touch my nose or put my hair behind my ears before I serve. That's possible to stop. Not putting the bottles in front of my chair, I could go without that, too. But adjusting my underwear, that I could never get rid of. It's impossible.

There’s no such thing as cheap food. It can be affordable, but it can never be cheap. I think that’s something we’ve been indoctrinated by fast food culture to believe, that it can be cheap – that it can be fast, cheap, and easy. But every culture since the beginning of time has thought of food as something precious, and that’s the way I think about it. I want to give my money to the people who take care of the land, and who grow that food.

I don’t think of it as research. I read for interest and enjoyment, and when I cease to enjoy it I stop. I didn’t research quantum mechanics but I was fascinated by the mystery that lies in the foundation of the observable world, of which the most familiar example is the wave/particle duality of light. I thought it was a good metaphor for human personality. The language of espionage lends itself to this duality—think of the double agent.

I don't enjoy it but I know that I have got to live with [myself] if I'm not going to give it 100 per cent. The key thing is getting to the start line and knowing that I couldn't have done any more, that I didn't back off. You accept the pain, because if you didn't there would always be that element of doubt.

All my life, I've gone through life anticipating trouble. And here I am, well along on my eighty-fourth year, and like Epictetus, I've had a favored life. It didn't make me unhappy to anticipate trouble all the time and be ready to perform adequately if trouble came. It didn't hurt me at all. In fact, it helped me.

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.

wisdom acquisition is a moral duty. It’s not something you do just to advance in life. Wisdom acquisition is a moral duty.

They win the respect, the deserved trust, of the people they deal with, and there is huge pleasure in life to be obtained from getting deserved trust. And so the way to get it is to deliver what you’d want to buy if the circumstances were reversed.

inversion frequently will solve problems which nothing else will solve. And in life, unless you’re more gifted than Einstein, inversion will help you solve problems that you can't solve in other ways.

Generally speaking, envy, resentment, revenge, and self-pity are disastrous modes of thought. Self-pity gets pretty close to paranoia and paranoia is one of the very hardest things to reverse. You do not want to drift into self-pity.
