In Thomas Hoerr's The Art of School Leadership we read the following:
Good leaders change organizations; great leaders change people. People are at the heart of any organization, particularly a school, and it is only through changing people - nurturing and challenging them, helping them grow and develop, creating a culture in which they all learn - that an organization can flourish. Leadership is about relationships.
Leaders increase a group's productivity by helping everyone in the group become more effective. Whatever the task or goal, a great leader helps everyone improve. A leader begins by setting the vision but doesn't stop there. A leader listens, understands, motivates, reinforces, and makes the tough decisions. A leader passes out praise when things go well and takes responsibility and picks up the pieces when things fall apart. Leadership is about relationships.
