One day you can be a kid, but another day you have to be like this is your job, you play tennis. You have to work for that.

Right now I like baseball, hockey and tennis players. And horseback riders.

I've always said I'm a good horse but I'm still an underdog.

I still think I have the speed and the variations also to win the matches, but its very good competition and also a great challenge for me too.

I have good anticipation, and good reaction to the the ball because I've played so many matches in my life.

I am number one in the world, so I have the right to be arrogant

The older you get, the more you learn.
