The late Oscar-winning director Sydney Pollack once told me that he was at a loss when he first moved behind the camera, so he simply acted like a director.
The feeling of not being up to the job, the belief that the role is too big, is something every leader has felt. It is evidence that the role is greater than the individual—and thus worth taking on. Pollack made the leader's requisite leap into the unknown, accepting the risk of failure that is the first step in becoming a leader—and he excelled.
That adaptive capacity is the most important attribute in determining who will become a leader. It's also the defining trait of the best actors. Inhabiting roles other than the one most of us think of as self is essential to both. So is the empathy needed to project yourself into someone else's skin.
Like great actors, great leaders create and sell an alternative vision of the world, a better one in which we are an essential part. Philosopher Isaiah Berlin wrote that Churchill idealized his countrymen with such intensity that in the end they rose to his ideal. Mahatma Gandhi made India proud of herself. Washington and the other Founding-Fathers shared that great leader's gift of making people believe they could be—and were—part of a great nation. Martin Luther King Jr. had that same genius.
When you consider such towering and theatrical leaders, you realize leadership may be the greatest performing art of all—the only one that creates institutions of lasting value, institutions that can endure long after the stars who envisioned them have left the theater.
