不要让昨天占据今天的太多时间。

Man is not logical and his intellectual history is a record of mental reserves and compromises. He hangs on to what he can in his old beliefs even when he is compelled to surrender their logical basis.

"We are all prisoners of our own memories, and the past is a jail from which we can never escape."

不要轻易放弃，因为你永远不知道下一秒会发生什么。
