"The serve is the most important shot in tennis."

人性的弱点总是充满贪婪、恐惧或者是愚蠢，这是完全可以预测的，但是我们无法预测这种人性弱点的发生顺序。

"The past is a shadow that follows us, but it is the light ahead that guides us."

However difficult life may seem, there is always something you can do, and succeed at. It matter that you don’t just give up.
