我认为没有什么比发明家看到自己脑中的创造逐渐走向成功时更令人心潮澎湃的了。

"Life is tough, my darling, but so are you."

The individual has become a mere cog in an enormous organization of things and powers which tear from his hands all progress, spirituality, and value in order to transform them from their subjective form into the form of a purely objective life.

有自知之明的人，遇到问题了会反省自己，不会抱怨别人；能够掌握自己命运的人，只会积极进取，不会抱怨苍天。
