Stupidity is a factor to be reckoned with in human affairs. The true leader always expects to encounter it, and prepares to endure it patiently so long as it is normal stupidity. He knows that his ideas will be distorted, his orders carelessly executed; and that there will be jealousy among his assistants. He takes these inevitable phenomena into account, and instead of attempting to find men without faults, who are non-existent, he tries to make use of the best men at his disposal - as they are, and not as they ought to be.
