A leader is someone who guides or directs other people. The opposite of a leader would be a follower. What compels someone to lead others? Someone who wants power or glory will step up and take the lead. Leaders want to have people below them. Some leaders want others below them, because they believe they are momentous. They want to set good examples. Other leaders want people beneath them so they can feel supreme and be a tormenter. Alexander the Great was the kind of leader who wanted to conquer the world to feel "great". He wanted to leave behind a properous nation. Sometimes, the biggest challenge is finding someone capable of filling the great leader's shoes once they are gone.
