Choose a specific health behavior that you would like to set as a goal for yours

Choose a specific health behavior that you would like to set as a goal for yourself or for someone else, and develop a strategy or program for change.
First, briefly describe the specific health behavior you are addressing and why you are addressing this behavior (e.g., your own attitudes, societal norms, medical information, fear of future illness).
Next, briefly describe the behavior-change approaches and supports that you think would be appropriate to maximize the chances of success (e.g., cognitive-behavioral elements, operant conditioning or reward systems, self-monitoring, social support, etc.).
How should stumbling blocks be addressed? Assuming success, how would you prevent relapse?
