Stay hungry, stay foolish.

Teach a man to fish.

Learn as if you will live forever.

Knowledge is power.

The unexamined life is not worth living.

Stay hungry, stay foolish.

I think, therefore I am.

The only thing we have to fear is fear itself.

温故而知新，可以为师矣。

三人行，必有我师焉。

博学之，审问之，慎思之，明辨之，笃行之。

不积跬步，无以至千里；不积小流，无以成江海。

读书破万卷，下笔如有神。
