I have created a set of laws I must follow to enforce self-discipline. One law is I will not steal candy from children. It sounds sort of weird to say "I broke my own law", and sounds sort of mathematical/unfitting to say "I broke my own rule".
Is there a more appropriate synonym for a self-created law? Furthermore, what would be an appropriate phrase to describe the set of laws I have created for self-discipline? A Code of Conduct? A doctrine?
The cooler the phrase the better, as it'll make the laws easier to follow.
