Napoleon Incentive
When one's own self inadequacies lead one to be more ambitious and successful. Similar to the Napoleon Complex, which states that one of short stature may be more aggressive and domineering. It is named after Napoleon because he was of short stature, but was massively ambitious and successful, which many shorter men have to do in order to make up for their short stature.
Brett suffered from the Napoleon Complex and was bitter. His friend, Dave, had a Napoleon Incentive and decided to become more confident and funny to compensate for his height.
