Boing Boing has a post about Michelle Singletary’s (syndicated personal finance columnist from the Washington Post) personal finance book "7 Money Mantras for a Richer Life."  In the post they list the seven mantras which I’ll just go ahead and list here for you:

Mantra #1: "If it’s on your ass, it’s
not an asset."
Mantra #2: "Is this a need or a want?"
Mantra #3: "Sweat the small stuff."
Mantra #4: "Cash is better than credit."
Mantra
#5: "Keep it simple."
Mantra #6: "Priorities lead to prosperity."
Mantra #7: "Enough is enough."

I particularly like #1.
