I feel old when I see mousse in my opponent's hair.

It's shocking how little there is to do with tennis when you're just thinking about nothing except winning every point.

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.

To be inspired - that's the secret.

Now that I've won a slam, I know something very few people on earth are permitted to know. A win doesn't feel as good as a loss feels bad, and the good feeling doesn't last long as the bad. Not even close.

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

First of all, let me say, 1:15 in the morning, for 20,000 people to still be here, I wasn't the winner, tennis was. That's awesome. I don't know if I've ever felt so good here before.
