眼睛看百步以内的东西，尚且没法看得一清二楚，而要把自己看见的就认为是实际有的，没有看见的就认为是没有的，这样的话天下所没有的东西，可就多了。

——〈民权主义第五讲〉，1924年4月20日

"Every moment is a fresh beginning."

Success is not about how much money you make, it's about the difference you make in people's lives.

I went to the woods because I wished 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.

不对称催化的美妙之处在于它能从简单中创造复杂。
