The value of psychology is in its power to explain life.
The natural effort of every individual to better his own condition, when suffered to exert itself with freedom and security, is so powerful a principle that it is alone, and without any assistance, not only capable of carrying on the society to wealth and prosperity but of surmounting a hundred impertinent obstructions with which the folly of human laws too often encumbers its operations.
译文:言语过多就会说错话,就容易招惹是非,争强好胜欲望多,就会烦恼不断。赏析:人要少说话,多做事,言多必有失,放一个平常心,顺其自然,行事更要低调。
