Once you have an idea of the things you would like to change about yourself, put them in an order from most important to least important. Resolve to start with the most important.   Remember that change is difficult. This means you do not want to attempt to change too many things at once. Furthermore, you may make the first change and realize that it is enough for you.

Making a plan to deal with foreseeable obstacles will help you deal with them as they come up.  For example, imagine you have several goals and it becomes too difficult to work on your top priority at some point. You might plan to work on another goal and return to the first one when circumstances are more favorable. For example, you may experience confusion or push-back from friends or family members....
