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

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'm not the best player in the history of tennis. I think I'm amongst the best. That's true. That's enough for me.

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.

For me, that's the most important thing, feel myself happy when I am playing. If I am healthy and I feel myself competitive, I am happy. Then is obvious I would like to win. But I know if I am in finals of important events, the normal thing is I finally win titles.

I doubt about myself. I think doubts are good in life. The people who don't have doubts I think only two things-arrogance or not intelligence.

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