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.

I don't expect never an easy match. I always expect difficult matches.

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.

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

I tried to find a solution to the problem that I had, tried to find a way to start playing better.

I have no sense of humor about losing

Certainly I would like to have some of the qualities of other players and obviously from Roger Federer. But believe me, there are plenty of other abilities that are important, particularly mindset and strength.
