The CEO is the captain of her ship. She is going to face many challenges, some of them from the sea, and some of them from the ship.
In assessing her role in a business, the CEO should be aware that some of the challenges her firm faces are a result of internal challenges – mutiny, broken masts – and others are external – high seas and fierce winds. The external challenges are outside of her control, and no one blames her for failures here. But the internal ones are inexcusable. Be the master of your own ship, the captain of your own destiny.
