How lovely it is to dream while you are awake.

It's easier to live with disappointment than regret.

Tennis is at an amazing time when you've got two of the best players ever to play the game. You can argue the two very best playing in the same generation. It's a rivalry I think that we've never seen in our sport.

If you're ranked number one in the world it's because you've earned it, and I think the only way to really get there is to have that ability and to have it nurtured in a very competitive environment at an early age.

You've got to believe you can win. But I believe respect for the fact that you can lose is what you always have to keep in mind so that nothing suprises you.

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 envy Pete Sampras's dullness. I wish I could emulate his spectacular lack of inspiration.
