    Eat healthier. Exercise twice a week. Read more books. Lose weight. We make the same resolutions (决心) every year, but most of us fail, dying out after only a few days or, at best, weeks. Even the most successful among us crash and burn when it comes to personal change. President Barack Obama struggles to get out of his cigarette habit.

Professionals who help people make changes in their lives suggest the change is decided not by one’s surroundings, but one’s mind. Beginning with small goals or steps usually leads to a better result later, they say. But they notice that the experience is different for everyone.

“People are more likely to make positive changes in their lives not only when their friends do, but when their friends of friends do, and when their friends of friends of friends do,” said Nicholas Christakis, a professor of medical sociology at Harvard University. “People are better able to make changes in their lives—lose weight, quit smoking, become happy—when they do this with a large number of other people, and so taking advantage of your social network ties can contribute to your own efforts.”

Johnny Augustin understands that well. His resolution for 2008 was to reduce 30 pounds from his 237-pound frame. But the change didn’t come easily. He said, “I’m a huge procrastinator, I kept putting it off until tomorrow. I didn’t get to do it until the summer.” However, Augustin got encouraged when he saw his older brother working out. Today, Augustin weighs 190 pounds.

“Of course, change can happen only if people don’t set their expectations too high or try to deal with too many changes at once; one of the biggest mistakes we make is setting unrealistic goals,” said Dalia Liera, a psychologist at Lesley University. “You can’t accomplish in a few weeks what you haven’t accomplished in a few years,” said Liera.
