No athletes talk to themselves like tennis players. Pitchers, golfers, goalkeepers, they mutter to themselves, but tennis players talk to themselves-and answer. Tennis players look like lunatics in a public square.

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

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.

If I don't do what I need to do to win, I won't win, no matter who is on the other side of the net.

It means a lot to you, to be out there. The highs are pretty high, and the lows are pretty low. You know, it's easy to feel like you let the team down. I mean, at the end of the day we still got to figure out a way to get through the tie.

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.

Sometimes it's just harder to remind yourself about what you're doing and why you're doing it... Other times, you have a great desire for it, but physically you're not responding the way you want. That presents other challenges. Then sometimes it all comes together.
