What I’ve achieved in tennis is great, but who I am as a person is more important.
A religion that gives nothing, costs nothing, and suffers nothing, is worth nothing.
A teacher must have a healthy body, the skills of a farmer, the mind of a scientist, the interest in art, and the spirit of social reform.
保持谦逊,保持渴望。
I don't believe in luck, I believe in hard work.
