Life is real，life is earnest.

The young do not know enough to be prudent, and therefore they attempt the impossible, and achieve it, generation after generation.

I believe that every performance should be unique and special.

我们今天做的每一个决定都塑造着我们留下的世界。

"The most important thing is to stay courageous."

A sustainable world starts with sustainable choices.

Stay hungry, stay foolish, but always stay true to yourself.

我必须研究政治和战争，以便我的儿子们可以自由地研究数学和哲学。
