Alexander the Great was known as a great leader, and he demonstrated why during a brutal trek through a desert. While all of his men were struggling with thirst, Alexander was offered water by one of his soldiers. Instead of drinking the water, Alexander asked the man if there was enough for the entire army. The solider replied that there was not, so Alexander poured the water on the ground. A great leader will not ask his followers to do something that he will not do himself.
