How are Your Resolutions Coming Along?

A classic study on resolutions found that 60% of people who set a New Year's goal give up on it within 3 months. But that means 40% succeed. The difference? Here are five steps to success:

1. Make a plan. Think ahead about what'll you do and when. And decide what you'll stop doing, so you don't over commit. You become what you think about ... and act on.

2. Believe you'll succeed. "Self-efficacy", belief that you can do it, comes from winning small challenges that lead to bigger ones. Begin a new exercise program by walking 10 min from your house (and then 10 min to get back) every other day. Then build on it.

3. Involve others. Studies show that getting people involved in your behavior change -- whether a trainer or friend to join you -- will help you stay focused and motivated.

4. Treat yourself. Build on step 2 by celebrating every success. If you stick to your exercise plan for two weeks, buy yourself a book or upgrade your shoes.

5. Never stop trying. Change is inevitable. Persist long enough, even with slipups along the way, and the likelihood of success tips heavily in your favor. Though only 40% quit smoking on their first try, another 20% stopped after more than six attempts.
