“A leader must be calm but not robotic.  It is normal—and necessary—to show emotion.  The team must understand that their leader cares about them and their well-being.  But, a leader must control his or her emotions.  If not, how can they expect to control anything else?  Leaders who lose their temper also lose respect.  But, at the same time, to never show any sense of anger, sadness, or frustration would make that leader appear void of any emotion at all—a robot.  People do not follow robots.” ~ Jocko Willink, Extreme Ownership (Page 275)
