A lot of times I had some problems, but I always had the passion and the personal motivation to keep going, to keep working hard, keep fighting for the things that really motivates me. That's all.

I admire a lot of people, but in terms of sport I've always loved the mentality of Tiger Woods on a golf course. I always love his eyes when he's setting himself and focusing on his decision; he has a really strong, focused face and believes that he can make the shot.

What distinguishes tennis is respect for one's opponent, one's conduct on the court.

If you are playing bad you are going to lose here, on clay, on ice, or on the beach.

I will do as I usually do. Tomorrow is going to be a day like any other day.

I only ever run when there's some point to it - say, if it's in a game of tennis.

I'll never have a tattoo - I just don't like them, and when you're old they can look a disaster. As for piercings, I don't like them on men.
