An effective leader is rarely judged to be a great leader by his immediate team. That is a judgment passed by a much wider audience and in the light of history. The leader must focus on getting the mission done. If he works hard to be popular or to be thought of as a great leader, he will often pay in the form of an unacceptable trade-off. He may be well liked, but he may not be as well accomplished.
As leaders, we must get the mission done. We do so through people. We need them to be influenced by us, but we do not need them to love everything about us.
