There are three things that influence how a leader should act. First the leader. That may be you. The leader must recognize his own abilities and how he can use his own personality to his advantage to influence a situation. Second is the led. The leader must know who he is leading, their personality and what motivates them. He must determine what strategies to use to influence the led. Third is the situation. No leadership style works in all situations. There is no magic formula that used in all situations works. So, the leader must be able to recognize the situation and determine what type of influence they will use.
A leader must know themselves and educate themselves on their followers. And determine what strategies will work in a certain situation.
