Character in many ways is everything in leadership. It is made up of many things, but I would say character is really integrity. When you delegate something to a subordinate, for example, it is absolutely your responsibility, and he must understand this. You as a leader must take complete responsibility for what the subordinate does. I once said, as a sort of wisecrack, that leadership consists of nothing but taking responsibility for everything that goes wrong and giving your subordinates credit for everything that goes well.
