"Young man," said the controller (who had always been a mentor to me), "you will learn one or two things, and this is a good time in your life to do it. First, if you want to be a leader, you must realize that a manager is not God. A manager does not create people - certainly not in his own image. As a manager you take people as they come, the way God created them, and you learn to work with them." He let the message sink in before he continued: "Second, in working with people, you should learn that it is inefficient to try to make up for their 'imperfections' (as you consider them) by working harder or longer hours yourself. By doing so, you may increase your output by 25 percent or 30 percent over a limited period. You might gain one-third of a man-year. However, if you create the conditions under which 10 people will each produce 10 percent more, you will have gained a full man-year."
