“Managers manage by using the authority the factory gives them. You listen to your manager or you lose your job. A manager can’t make change because that’s not his job. His job is to complete tasks assigned to him by someone else in the factory.
Leaders, on the other hand, don’t care very much for organizational structure or the official blessing of whatever factory they work for. They use passion and ideas to lead people, as opposed to using threats and bureaucracy to manage them.”—Seth Godin: Tribes: We Need You to Lead Us
