New Year's resolutions are a bit like babies: They're fun to make but extremely difficult to maintain.
Each January, roughly one in three Americans resolve to better themselves in some way. A much smaller percentage of people actually make good on those resolutions. While about 75 percent of people stick to their goals for at least a week, less than half (46 percent) are still on target six months later, a 2002 study found. It's hard to keep up the enthusiasm months after you've swept up the confetti, but it's not impossible.
This year, pick one of the following worthy resolutions, and stick with it. Here's to your health!
