I only ever run when there's some point to it - say, if it's in a game of tennis.

I used to wear sleeveless T-shirts all the time on court, but now I've got a brand new look - I've moved on to polo shirts. Sleeveless T-shirts give you real freedom of movement and they keep you cooler in matches, but I just thought it was time for a change.

Playing well or playing bad, I have to play aggressive. I must play aggressive.

Even if I have already peaked, I have to believe I can improve. I wake up every morning, and go to practice, with the illusion that I'm going to get better that day.

I doubt about myself. I think doubts are good in life. The people who don't have doubts I think only two things-arrogance or not intelligence.

I will work day after day like I did my whole life ... I'm not going to change anything.

It's the same old story, all you think about is money.
