I think to be 'tough' means you look relaxed. So you have to be tough to win tournaments. But you don't want to be so tough on yourself.

As it becomes longer at No. 1, I feel more and more pressure. Everybody is trying to grab every piece of me.

When I was 13 my dream was to play the U.S. Open. Now it's to win it.

I feel I am very fortunate to have a job that I really like.

When I'm out there, I don't think about anything. I just grip it and rip it. I don't like to worry about technique.

I just want to show the fans my big smile and play the game that I love.

I love various sports, including basketball, tennis and billiards.
