I had my moments for sure but I wasn't confrontational. And sometimes you get on the court and you'd find yourself very confrontational. It was all a discovery.

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've been criticized for not having perspective in the past and I thought that of myself many times but not there.

I play tennis for a living even though I hate tennis, hate it with a dark and secret passion and always have.

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.

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

Tennis is one of the only sports in America where the sport doesn't grow with the size of the person - it just forces you to swallow the whole pill.
