The Wind. The rush of unexpected events, and the doubts and criticisms of those around you, are like a fierce wind at sea. It can come from any point of the compass, and there is no place to go to escape from it, no way to predict when and in what direction it will strike. To change direction with each gust of wind will only throw you out to sea. Good pilots do not waste time worrying about what they cannot control. They concentrate on themselves, the skill and steadiness of their hand, the course they have plotted, and their determination to reach port, come what may.
