人格在你20多岁时比在人生的任何其他时期都更容易改变。

"The only person you should try to be better than is the person you were yesterday."

有时候，旅程教会你很多关于目的地的事。

知识是力量的源泉。

The end of history will be a very sad time. The struggle for recognition, the willingness to risk one's life for a purely abstract goal, the worldwide ideological struggle that called forth daring, courage, imagination, and idealism, will be replaced by economic calculation, the endless solving of technical problems, environmental concerns, and the satisfaction of sophisticated consumer demands.

所有人的生活里都有一部历史。

你无法取悦所有人，所以做你自己就好。
