So I looked at this dilemma and created four useful suggestions to increase the probability that your New Year's resolutions will stick this year. Sometimes we are just too vague about what we want. It is too vague. What would your ideal weight be, less what do you weigh now, is what you are going after. Set a deadline.
Deadlines are commitments.
Without a deadline as a self-imposed pressure point, getting started is easily postponed. You see, deadlines put us on the line and define when failure occurs. Deadlines also help us to break the resolution down into little bite-sized pieces. Now that's manageable. 500 calories a day is easy to achieve.
