"To live is the rarest thing in the world. Most people exist, that is all."
Life is short, make it sweet.
The best way to predict the future is to invent it.
The moment you doubt whether you can fly, you cease for ever to be able to do it.
我不会让世界定义我的成功。
I don’t see myself as a superstar. I see myself as a normal guy who loves tennis.
