I am a very positive thinker, and I think that is what helps me the most in difficult moments.

I'm as patient a father as I am on the tennis court. It takes a lot for me to get really upset, but sometimes kids can get you really cross if they really keep bugging you.

Oh, my God, I don't think any player can look forward to or expect to a career of so many Grand Slam wins or title wins or being so long at the top of the game.

I can't stay No. 1 for fifty years, you know. We'll see what happens.

It doesn't need to be the same every day, doesn't need to be the same shower I use, the same restaurant I go to, the same hour I go to sleep. I've always been very flexible. I don't care if I practice at nine in the morning or 10 P.M.

You've never seen me dance, have you?

Sometimes you have to accept that a guy played better on the day than you.
