If you are healthy, you can work. If you can work, then the chances of success are higher.

I learned during all my career to enjoy suffering.

My uncle developed the training philosophy. His idea of good tennis training is basically quite simple: you must try to gain time.

I have the same bedroom I've always had. It's clean and tidy when I get home, and after two or three days it gets messy and my mother nags me.

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

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.

That's painful always to lose.
