If there is a deadline, one meets it. If there are stated policies, one keeps them. Leadership, however, is the development and articulation of a shared vision, plus the engagement of those without whom that vision cannot become a reality. Administration and management are required for effective leadership, but one can administer and manage without vision and shared values. Leadership is always a moral act.
Leadership is also confused with authority or position.
Think, instead, of leadership as calling. It is not that no one else could do it, but right now it is my calling. It is what God and others expect of me. If leadership is discerned as calling, all of us are leaders and all of us are followers. The key is to know when to be which.
