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.

Honesty, willingness to exert oneself, friendship - all these things shaped me too.

It is important to recognize the small successes.

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

It's hard to say, 'I don't believe in God.' I would love to know if God exists. But it's a very difficult thing for me to believe.

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.

When one player is better than you, at this moment, the only thing you can do is work, try to find solutions and try to wait a little bit for your time. I'm going to wait and I'm going to try a sixth time. And if the sixth doesn't happen, a seventh. It's going to be like this. That's the spirit of sport.
