For sure, with golf it's not a physically demanding sport like tennis. That's what makes tennis great - you combine both things. It's a very mental sport and at the same time can be dramatically physical. But I do admire the mentality of sport more than the physicality because physical performance is much easier to practice than mental performance.

Some people get very confused about my game. They think it's better if the court is slow, because I have a good defence. But the faster it is, the better for me. My spin is more painful for my opponents, my aggressive game works better.

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.

I love the crowds in Miami. I feel that is one of the tournaments where I get more support. That helps me a lot.

My uncle developed the training philosophy. His idea of good tennis training is basically quite simple: you must try to gain time.

You have to accept both losing and winning well. I've stayed calm when I'm winning and I've stayed calm when I've lost.

When one gets beaten by somebody better, one has to know how to lose with humility. Sure, I could have served better. Sure, I could have hit my forehand harder. But the truth was this was like an avalanche, and there was no way to stop it.
