Grade yours on a 10-point scale.

Nobody's perfect. When it comes to our financial lives, we've all done things we later regretted -- whether it's getting slapped with a $3 fee for using an out-of-network ATM or going on a Las Vegas bender and losing the house on an overly aggressive poker bet.

The key is to understand the scale of the transgression. With credit card blunders, that's no easy task -- is it worse to take a cash advance or to pay a bill a day or two late?
