"There are really two things that drive New Year's resolution success. Number one is telling somebody about your goal. Chances are, they'll either join you in pursuing it or at least support you. Number two is to be concrete and specific. You don't want a goal like "becoming a better person," because there's no objective way to judge that. It's got to be something like "I'm going to call my mother once a week." Or "I'm going to cut my body mass index to 25." It can't be fudgeable."
