Man is the measure of all things: of things which are, that they are, and of things which are not, that they are not.
人是万物的尺度：对于存在的事物，它们存在；对于不存在的事物，它们不存在。
The best banking service is invisible but always available.
The most difficult thing is to be simple.
耐心是智慧的伴侣。
——在遗嘱上签名后，对在病榻的同志们说，1925年3月11日
No matter what you’re going through, there’s a light at the end of the tunnel.
