我是一个非常积极的思想者，我认为这是我在困难时刻最能帮助我的东西。

The only way to avoid being miserable is not to have enough leisure to wonder whether you are happy or not.

All the choir of heaven and furniture of earth - in a word， all those bodies which compose the frame of the world - have not any subsistence without a mind.

成功不是幸福的关键。幸福才是成功的关键。

唯一真正的智慧在于知道自己一无所知。

Life is too short to be anything but happy.

永远不要停止学习，因为世界从未停止变化。
