Ego Is the Enemy draws on a vast array of stories and examples, from literature to philosophy to his­tory. We meet fascinating figures such as George Marshall, Jackie Robinson, Katharine Graham, Bill Belichick, and Eleanor Roosevelt, who all reached the highest levels of power and success by con­quering their own egos. Their strategies and tactics can be ours as well.
