最好的艺术来自痛苦。

诗人的使命是照亮黑暗。

The best businesses solve real problems. Find a need and fill it.

The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.

I went to the woods because I wanted to live deliberately. I wanted to live deep and suck out all the marrow of life. To put to rout all that was not life. And not, when I had come to die, discover that I had not lived.

我们不是七个人和你，我们是一体的。

The purpose of abstraction is not to be vague, but to create a new semantic level in which one can be absolutely precise.
