A proven motivator will make it to the top before a proven genius. When Andrew Carnegie hired Charles Schwab to administer his far-flung steel empire, Schwab became the first man in history to earn a million dollars a year while in someone else's employ. Schwab was once asked what equipped him to earn $3000 a day. Was it his knowledge of steel manufacturing? "Nonsense," snorted Schwab. "I have lots of men working for me who know more about steel than I do." Schwab was paid such a handsome amount largely because of his ability to inspire other people. "I consider my ability to arouse enthusiasm among the men the greatest asset I possess," he said, and any leader who can do that can go almost anywhere and name almost any price.
