I like my groundstrokes, I can say. I like it. That's my game - I'm a groundstroke player and I play pretty aggressive.

I had to listen to the classical music because it calms me down, calms my nerves down.

Not everybody can like what I do, and if you feel that somebody is coming up closer to you and starting the rivalry and everything, you maybe change your position to him.

Mangling my racket and an odd swearword on the court is not something I am proud of and it shouldn't happen, but even my coaches have told me that it's sometimes better to let it all out, the anger inside you, because keeping it bottled would just eat you up in the long term.

It has been the best thing that has ever happened in my life.

In my case, I can sincerely say that nothing is impossible... When I was saying I want to be No. 1 of the world, and I was seven or eight years old, most of the people were laughing at me because it seems like I have one percent of chances to do that, and I've done it.

Tennis is my life, obviously; I need to focus, I need to win. But it's not the only thing. I'm not going to play forever.
