I Need Your Help: How Do People Change?

About a year ago, I conducted an informal survey via Facebook on the following question: Why DON'T people change despite knowing that it would be in their best interest? I appreciated all of the great responses!

At the present moment, I would like to pose a similar, yet much different, question: How DO people change knowing that it is in their best interest? In other words, how do they work through fear, resistance, apathy, rationalizations, ambivalence, laziness, etc.?

Please post your reply on the blog or Facebook or Twitter.

Thanks in advance for your help!
