Benjamin Franklin writes about how he started a process of self improvement by focusing on various virtues:

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; ie, waste nothing.
6. Industry - Lose no time; be always employed 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, clothes, or habitation.
11. Tranquility - 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.

[It is good to follow these rules. They can make life too good and too peaceful.]
