The ball is round, the game is long.

My greatest point is my persistence. I never give up in a match. However down I am, I fight until the last ball. My list of matches shows that I have turned a great many so-called irretrievable defeats into victories.

I was fascinated by a compelling character embroiled in a controversial topic that told the story from a different point of view.

I play tennis five hours a week, from Monday to Friday, for one hour every day. I like to be fit. If I can't exercise, I feel bad - I need to sweat and run to feel like I'm in good shape.

It's tough when you're No. 1. You don't have any private life, you can't even walk anywhere. I think that was one reason why I lost my motivation to play tennis.

I'm amazed that years after I stopped playing tennis, people still recognize me in restaurants and ask for my autograph.
