Tennis is a funny game; unbelievable highs and the lows are just as low.

You can tell when someone has been on steroids A guy bulks up, has a new body and never gets tired...You see these guys or girls who come onto the tour talking about their new training programs and their diets where they eat this or that new thingbut they'll never tell you about the drugs they took.

There's too much money and too many nice guys around.

I want to be remembered as a great player, but I guess it will be as a player who got angry on a tennis court.

If Roger stopped right now and never won another match, to me he'd already be one of the greatest players to ever play the game. To me, he's the greatest all around talent that I've ever seen.

If, in a few months, I'm only number 8 or number 10 in the world, I'll have to look at what off-the-court work I can do. I will need to do something if I want to be number 1.

There's something deeply satisfying when it succeeds, but I'm not going to do another book just to put my name on something and make some money if it's not something I deeply care about.
