做你自己；别人都已经有人做了。

The past is a shadow that follows us, no matter how fast we run.

世界不会记住你说过什么，但会记住你做过什么。

如果流动，就流走；如果静止，就干涸；如果生长，就慢慢凋零，这个世界没有永恒。

If we find the answer to why the universe exists, it would be the ultimate triumph of human reason – for then we would know the mind of God.

Sometimes we get sad about things and we don’t like to tell other people that we are sad about them.

有时候你必须做你必须做的事情才能生存。
