我不在乎你对我的评价，只要那不是真的。

你的价值不会因为别人看不到你的价值而降低。

"When you do something best in life, you don’t really want to give that up – and for me it’s tennis."

永不，永不，永不屈服。

The world is so unpredictable. Things happen suddenly, unexpectedly. We want to feel we are in control of our own existence. In some ways we are, in some ways we're not. We are ruled by the forces of chance and coincidence.

I'm not afraid to say what I feel, and I'm not afraid to be who I am.

我是那种会一直坚持下去直到成功的人。

The higher the expectations, the harder I work.
