Self-regulatory failure: Programs for constructive change, even those that start strong, often dwindle and disappear.
False hope: People often believe that they can change more than they actually can. That is, their goals are unrealistic. False expectations lead people to reject more modest goals that they could actually achieve.
Discretionary change: Change that is not forced in one way or another is poor.
Decay curve: Attrition, noncompliance, and relapse are the name of the game. Many people think that change will be easy.
People are often unrealistic about how life-enhancing successful change efforts will be.
