The 'problem' with willpower is not temptation. Temptation is only a problem for those with no willpower who paradoxically want to believe that they do. There are two solutions. Either study philosophy and come to understand why you act the way you do and seek to modify that if desired... or actually evaluate the real consequences of your actions and decide if whatever their label might end up being whether the consequences are actually worth being worried or ashamed about. Most often, people are worried about things that harm no one, making their worry absolutely meaningless.
