Think back to any time you’ve looked at your credit card statement and decided that your huge balance was just because of “an especially crazy month.” Maybe your surprise charges looked something like this: A gift for the wedding you attended, that GoFundMe donation for your coworker’s daughter, a new tire after you drove too close to the curb to avoid that pothole (both came out of nowhere!), and—gah!—a last-minute suit for that wedding because your old one is two sizes too big (the only downside to hitting your weight loss goal).
