My father believed in me many times more than I believed in myself.

I don't think, that you can always - you can ever - get your game to perfection, you know. Only if you're Federer.

I always try to have something that keeps my mind relaxed, keeps my mind a little bit off tennis.

Joking around is part of my personality, just who I am.

I'm happy, my family's happy, everything is going well.

In my case, I can sincerely say nothing is impossible.

In terms of playing ability there is nothing to choose between number one and 100. Instead, it's a question of who believes and who wants it more? Which player is mentally stronger? Which player is going to fight the hardest in the big points? These are the things that determine who is the champion.
