In 1726, at the age of 20, Benjamin Franklin created a system to develop his character.
In his autobiography, Franklin listed his thirteen virtues as:
1. Temperance: Eat not to dullness; drink not to elevation.
2. Silence: Speak not but what may benefit others or yourself; avoid trifling conversation.
3. Order: Let all your things have their places; let each part of your business have its time.
4. Resolution: Resolve to perform what you ought; perform without fail what you resolve.
5. Frugality: Make no expense but to do good to others or yourself; i.e., waste nothing.
6. Industry: Lose no time; be always employ’d in something useful; cut off all unnecessary actions.
7. Sincerity: Use no hurtful deceit; think innocently and justly, and, if you speak, speak accordingly.
8. Justice: Wrong none by doing injuries, or omitting the benefits that are your duty.
9. Moderation: Avoid extremes; forbear resenting injuries so much as you think they deserve.
10. Cleanliness: Tolerate no uncleanliness in body, cloaths, or habitation.
11. Tranquillity: Be not disturbed at trifles, or at accidents common or unavoidable.
12. Chastity: Rarely use venery but for health or offspring, never to dullness, weakness, or the injury of your own or another’s peace or reputation.
13. Humility: Imitate Jesus and Socrates.
