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 will keep smiling, be positive and never give up! I will give 100 percent each time I play. These are always my goals and my attitude.

It's hard to always be on top. You go down, you go up.

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.

You learn something when you don't play well, and I figure that helping people, it makes me very, very happy.

I have the picture in my mind of how emotional I will feel if I win again.

I have a fearless but neutral personality.
