本杰明·富兰克林，美国科学家，政治家，外交家，美国独立宣言和宪法签署人，作家，出版家，成功的印刷厂主。据说这13条美德是他在20岁时自己制定的，每周努力实习一项，到13周后重来一遍。（本来想翻译，仔细看过却觉得不如放在这里学英文）

1. Temperance: Eat not to dullness and drink not to elevation.
节制：不要吃得像个傻子，也不要喝得飘飘然。

冷静：不要让琐事，普通或不可避免的事故来扰乱自己。

13. Humility: Imitate Jesus and Socrates.

（第9条中间应该是forbear，而不是forebear。这些美德记录在富兰克林的自传当中。这个网站上的文本是这个写法，其他可以Google到的几乎全错了。）
