发现可能性的极限的唯一方法是超越它们进入不可能。

If you want to be the best, you have to do things that other people aren't willing to do.

"Tennis is a sport where you have to be strong mentally and physically, but the mental part is even more important."

No matter what happens in life, be good to people. Being good to people is a wonderful legacy to leave behind.

The chief beauty about time is that you cannot waste it in advance. The next year, the next day, the next hour are lying ready for you, as perfect, as unspoiled, as if you had never wasted or misapplied a single moment in all your life. You can turn over a new leaf every hour if you choose.

如果你发现自己在想 "咦，我的好刀呢？”或者“我的好笔在哪里？" 这意味着你有的是坏的东西。把坏的扔掉吧。
