To be a great leader, one must care about their role and the duty that it holds. A leader is fundamentally responsible for those that they lead. From their health and safety to their professional and personal development and the quality of the work products they create, a leader must be constantly focused on the people they serve. A great leader is more concerned about the service they can provide to those they are entrusted to lead than they are about what their subordinates can do to advance their own ambitions. It really is a matter of perspective about the role of a leader and who is their primary constituents.
