What I’ve achieved in tennis is great, but who I am as a person is more important.
我在网球上取得的成就是伟大的,但我作为一个人是谁更重要。
To truly grasp the nature of reality, one must first accept the limitations of human perception.
You may think I’m small, but I have a universe inside my mind.
I'm not going to compare myself to anybody. I'm going to do the best I can do. I'm going to work hard every day to be the best that I can be.
