“In order to convince and inspire others to follow and accomplish a mission, a leader must be a true believer in the mission.  Even when others doubt and question the amount of risk, asking, ‘Is it worth it?’ the leader must believe in the greater cause.  If a leader does not believe, he or she will not take the risks required to overcome the inevitable challenges necessary to win.  And they will not be able to convince others—especially the frontline troops who must execute the mission—to do so.” ~ Jocko Willink, Extreme Ownership (Page 76)
