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.

What I learned as a young child continues to have a tremendous impact on my life today.

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.

I don't think there has been enough communication between the players and the tournaments. In one sense it's just as much the players' fault. Players talk between each other and in the locker room about things that can be improved and then when the time comes to talk and really do something about it they stop.

My father never talked about the sacrifices that the family made for me.

Each year represents new challenges and obstacles. You have to adjust.

I embraced, I think, the process of becoming No. 1 of the world, which was long and difficult, but it's sweeter in the end.
