The first is to understand the magnitude of what you're resolving. Serious resolutions demand character change, personality change. That's a big deal. It's how I act, how I see myself, how I see others. Of course there are differences between you and an addict.
Addicts are sick.
You think you're in pretty good health. Still, sometimes a seemingly tossed-off resolution reflects a serious underlying health issue. Maybe you are slouching toward obesity, a major medical risk for heart disease and diabetes. Like the addict, you may be hostage to the part of your brain that drives you to eat when you're not necessarily hungry. Unchecked, that kind of single focus is likely to lead to the doctor's office for stress-related complaints.
