I try to enjoy what I do, and every moment of the life that I have is a blessing. What else can you do but to be happy and try to bring that joy to the other people around - especially in the tournaments. Everybody has bad days. I'm not always funny or laughing.

My success has a lot to do with my private life. I've matured a lot by first becoming a husband and now a father. My life is in the right direction. And that helps a player to thrive. One thing is linked with the other. My private life has helped me.

Nadal's the best player in history on [clay], and he is one of the best-ever players that played this game.

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

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

No, I have something else between my legs.

I have always valued the care for my body, and my mind and had holistic approach to life. I always thought this is utmost importance for my tennis.
