Over time the constant modifications to behavior accumilate makeing new modifications more easily implimented. This produces A higher level of exisistance for the person implimenting these changes and brings the into a more harmonius and spiritual state of being. Not to mention all the stress and anger that is avoided. Another one of the ways in which a driving personality makeover allows us to create changes in our lives is through cognative dissonance. By making us consciously focus on what we're doing wrong, cognitive dissonance provides motivation for bringing our actions in line with what we know to be the right choice.
Cognitive dissonance motivates efforts to reduce in consistancy in our thoughts and actions.
I also think that a driving personality makeover helps create changes by focusing on individual behavior and thus forces us to deal with Actor-observer bias. Actor-observer bias is our tendency to infer external causes for our own behavior and internal causes for others' behavior.
