I was passionate about soccer. I still am. Odd, though - playing soccer always made me much more anxious than playing tennis. On soccer days, I'd be out of bed by 6 in the morning, all nervous. But I was always calm when it was time for a tennis match. I still don't know why.

The young athletes are supposed to mature, to improve their personality.

It's more a tennis problem than a mental problem. The transition is difficult. It depends how much time you have. Playing on grass can sometimes be a bit of a lottery.

I don't think about how going to be the match. I think about try to do the right things to win. I don't think about how easy can say or how tough can say. I go on court. I try my best.

Losing is not my enemy..fear of losing is my enemy.

Even if I have already peaked, I have to believe I can improve. I wake up every morning, and go to practice, with the illusion that I'm going to get better that day.

It should not be a child's only goal to become the best player in the world. That would be a bad, a harmful attitude.
