Stay humble and work hard.

"The only thing that is truly timeless is the human story."

There is no better teacher than history in determining the future……There are answers worth billions of dollars in a history book.

We don't have to try so hard.

道德规则不是我们理性的结论。

Never close your lips to those whom you have already opened your heart.

追求知识是一段永无止境的旅程，每一个发现都为新的问题打开了大门。
