Life is nasty, brutish, and short.

He who is not contented with what he has，would not be contented with what he would like to have.

In the end, we only regret the chances we didn’t take.

The tears of the world are a constant quantity. For each one who begins to weep, somewhere else another stops. The same is true of the laugh.

鸟有巢，蜘蛛有网，人有友谊。

我确信宇宙中充满了智慧生命。只是它们太聪明了，不会来这里。
