One should just be able to play a perfect game.

I enjoyed the position I was in as a tennis player. I was to blame when I lost. I was to blame when I won. And I really like that, because I played soccer a lot too, and I couldn't stand it when I had to blame it on the goalkeeper.

Every match I go into, I'm the huge favorite. I lose a set and it's, like, crazy.

Once you find that peace, that place of peace and quiet, harmony and confidence, that's when you start playing your best.

There is no way around the hard work. Embrace it.

My dad said if you become a tennis professional just make sure you get into the top hundred, because you have to make a little bit of money. You make a living so you can pay your coaching and, you know, your travels.

I've always been aware that the image you patiently construct for an entire career can be ruined in a minute. It scares you a bit, but that's the way things are.
