快乐是生活的关键。没有快乐，你就一无所有。

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

The test of a first-rate intelligence is the ability to hold two opposed ideas in the mind at the same time, and still retain the ability to function.

And gladly would learn， and gladly teach.

In despair, we can find true hope.

我们的人生如同被讲述的故事一样度过。

最好的公司是那些为真实的人解决真实问题的公司。
