As tennis players, we work and we sacrifice many things. To lose, that's not a happy thing - I mean sure, I was disappointed. You have to come back strong. But to win the last point in a grand slam tournament, that's the most beautiful and most satisfying feeling you can get as a tennis player. It's worth it.

I just hated to lose.

Basically I started playing double handed on both my forehand and backhand side because my first racket was very heavy.

It has changed, quite a lot. It is very different now, there are quicker men, they are taller, stronger, have great stamina. The balls have also become faster. Tennis has now become a power sport. There is more depth in the game, as well, there are many more players than there used to be. The entire character of the game has changed.

Roger Federer is stylish.

My greatest point is my persistence. I never give up in a match.

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.
