Leaders get the job done and keep the group going. Leaders have a special title or badge that makes others like to follow. We'll take the third one. Leadership is not magic that comes out of a leader's head. The leader learns how to get the job done and still keep the group together.
Leadership differs with the leader , the group , and the situation .
No leader can take over another leader's job and do it the same way. Groups are different, too. A great football coach might have difficulty leading an orchestra. A good sergeant might be a poor Scoutmaster. So when a leader changes groups, he changes the way he leads.
