As a tennis player, you have to get used to losing every week. Unless you win the tournament, you always go home as a loser. But you have to take the positive out of a defeat and go back to work. Improve to fail better.

For me, motivation is easy. I enjoy what I'm doing, and I'm lucky to play tennis. I enjoy the suffering. It's something quite natural for me to go on the court and suffer, and to go in the gym and to suffer, and to know the only way to get better is to work out - that's what I like.

There's a lot of ingredients go into being a good tennis player.

As a tennis player you can win and you can lose, and you have to be ready for both. I practised self-control as a kid. But as you get older they both - winning and losing - get easier.

It's always good to play tennis with a better player to bring out the best in you.

My favorite tennis player, who I'm amazed by, is Roger Federer.
