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.

I'm going to have to pick my shots and play great tennis.

Pride is bad, stress is good. I don't want to feel confident. I want to feel rage. Endless, all consuming rage.

If I don't do what I need to do to win, I won't win, no matter who is on the other side of the net.

First of all, in any sport where you can measure distance, height speed and all of that, you see how athletes have changed their sport and made it better. I believe, with every generation, the sport has improved. Certainly, in the men's game, that has been the case. I think that I played Pete [Sampras] at his best, I played Roger [Federer] at his best.. I believe wholeheartedly that Roger and [Rafael] Nadal have pushed the game much further than myself or Pete ever did. Their options on the tennis court are considerably more than ours.

The best predictor of future events is probably past events.
