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

It is very important and my success very much depends on the harmony that I feel in my private life. It is essential for me to be happy in my private life. And if it continues, I am able to continue playing tennis.

My priority, the most important thing in my life is my family, my wife and my son.

I cannot guarantee anything.

I'm a happy man, because I am successful in what I do, of course; but what makes me most happy is I have people around me that I love and who love me back. This, for me, is the most important thing. Nobody likes to be alone.

I still feel young as far as motivation is concerned, and also the challenges that I have for the future and what I want to achieve. So I just hope this successful streak is extended to the fullest.

My mother is a special story. She went through so much to bring us up, four men at home, especially when our country was going through really difficult times.
