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

When you play good, everything is good, but when you dont play so good, everything is bad. Even when you think there are good things, they still say bad things.

It's easy to have a good season but if you want to have a great season you have got to win a major tournament.

You always learn something from mistakes.

You need to take care of your time and practice, you need to rest and talk to media. So it's really important to organize those things.

At that time, I feel sad, and I feel no one knows how hard I work and how many tears. They only know the score. At that time, I feel very lonely because no one understands since they haven't been world No. 1 before.

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.
