World history can be best written by evaluating the lives of great leaders as well as bad leaders and what they accomplished through others. Leaders can, on one hand, influence men and women to do great things. Simultaneously, they also have the power to do great damage to their followers by the mistakes they make. Leaders have incredible power to perform good or ill in people's lives. Our confidence in our leaders begins to erode quickly.
People resign and walk.
Leaders are fired and division, strife and backbiting reign. The work, whatever it is, is slowed, damaged or comes to a screeching halt. Because most of us who lead have never been formally trained nor have good role models. So, we lead as we are led. We wing it.
