我从不买任何东西，除非我能给自己一个充分的理由为什么要买它。

As to the gods, I have no means of knowing either that they exist or that they do not exist. For many are the obstacles that impede knowledge, both the obscurity of the question and the shortness of human life.

不要害怕失败，害怕的是你连尝试都不敢。

成功的秘诀就是不断前进。

"The only real progress lies in learning to be wrong all alone."

Consciousness is the theater where survival strategies are played out.
