Benjamin Franklin's Plan of Conduct

We would all do well to apply these four principles (though there are many others I can think of to add!)...

1) It is necessary for me to be extremely frugal for some time, until I have paid what I owe.

2) To endeavor to speak truth in every instance; to give nobody expectations that are not likely to be answered, but aim at sincerity in every word and action -- the most amiable excellence in a rational being.

3) To apply myself industriously to whatever business I take in hand, and not divert my mind from my business by any foolish project of growing suddenly rich; for industry and patience are the surest means of plenty.

4) I resolve to speak ill of no man whatever, not even in a matter of truth; but rather by some means excuse the faults I hear charged upon others, and proper occasions speak the good I know of everybody.

This is also a great quote to keep in mind:

"Sin is not hurtful because it is forbidden
But it is forbidden because it's hurtful.
Nor is a duty beneficial because it is commanded,
But it is commanded, because it's beneficial."

-Benjamin Franklin
