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 father had never watched tennis, never liked tennis too much. He said, 'OK, we buy a racket, we watch together,' because we didn't know anything. It was a process of learning together that made it more interesting.

I understand that the results I've had in my career, or I'm having now, they are very good. And that gives me confidence, of course, but I do not feel invincible.

I stopped thinking too much about what could happen and relied on my physical and mental strength to play the right shots at the right time.

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.

My strokes just weren't there.

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.
