I played almost four hours today, ... Im very, very tired.

It's the same old story, all you think about is money.

My goal is to improve my game, stay healthy and be competitive. If I have that, I know I can be able to win tournaments, which in the end is what it counts.

I am satisfied the way that I am playing. Is obvious that there is always things to improve.

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.

I think I am a complete player. I can play well on all the surfaces. For me, the clay might be easiest, but I am not a specialist on clay.

I am not the most courageous guy in the world outside of the court.
