My serve can get better, for sure. It's not just about serving bombs, but positioning, variation in speed, in spin.

The glory is being happy. The glory is not winning here or winning there. The glory is enjoying practicing, enjoy every day, enjoying to work hard, trying to be a better player than before.

Some people may learn something from the way I play tennis. But there are also players who are better than me in certain techniques.

If you want to belong to the best, you need good technique and, perhaps even more importantly, a good eye. If you see the ball sooner, you have more time to think about how and where to return it.

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

I have no sense of humor about losing

If I am not playing at one hundred percent, it is going to be very difficult for me to win.
