"Throughout his ministry Moses is continually exasperated with the children of Israel. Their moaning, groaning, and whimpering drive him crazy. So great is his frustration that he takes it to God: "Am I a mother that I need to coddle these people through the wilderness?" Later in his ministry we hear him pray, "God, if you are at all merciful, let me die here on the spot. Do not let me view my own misery any longer." Moses was burned out, and burnout is what we fear most for introverts who operate in an extroverted role. They simply do not have the capacity to hang in there with people without taking large chunks off by themselves."
