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.

Big dreams are so damn tiring.

I can live with losing, I can't live without taking my chance.

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.

Tennis is a very objective sport in the sense that the scoreboard doesn't lie.

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

Hitting the ball has never been my issue, so I can literally not pick up a racquet for two months and hit the ball, really, really nicely. I mean movement's always an issue.
