"It’s not so much New Year’s resolutions themselves but what lies underneath the seemingly innocuous act of making them that needs to be re-evaluated. Down deep, every one of us longs to be loved, accepted, appreciated, respected, and so on. We want our lives to count. And we conclude that if we’re going to experience these things, we have to make it happen by doing more, trying harder, losing weight, behaving better, etc. In other words, underneath our New Year’s resolutions is the drive to save ourselves by generating our own value, significance, meaning, and security by what we do and by who we can become."
Beware that "seemingly innocuous act" of resolving to improve yourself.
