"Tennis is a sport where you have to be strong mentally and physically, but the mental part is even more important."
相信自己和你所拥有的一切。
美始于你决定做自己的那一刻。
The world owes all its onward impulses to men ill at ease; the happy man inevitably confines himself within ancient limits.
Keep your head up, God gives his hardest battles to his strongest soldiers.
