A great coach can lead you to a place where you don't need him any more.

Freed from the thoughts of winning, I instantly play better. I stop thinking, start feeling. My shots become a half-second quicker, my decisions become the product of instinct rather than logic.

Sex doesn't interfere with your tennis; it's staying out all night trying to find it that affects your tennis.

I don't always choose to stay fit by playing tennis, because that comes with its own wear-and-tear.

It has meant a lot to me to challenge the best players in the world and to beat them. And it means a lot to me to be out here and fighting for the title and, you know, it hurts not to win it.

Nothing can substitute for just plain hard work. I had to put in the time to get back. And it was a grind. It meant training and sweating every day. But I was completely committed to working out to prove to myself that I still could do it.

Every now and then I will play; I try to focus on charitable work. I might do it because it's an offer I can't refuse, so I rally and try to stay in shape and keep myself active.
