How do I put down the weight of everyone's safety when I land?

You handle emergencies well. That is not in question. The question is what you do with the calm hours—the ones on the ground, with your family, in your own bed. If you are still bracing for the next crisis then, you have confused your job with your whole life. No one asked you to guard the world at all hours. They asked you to guard the cabin, for the length of the flight. When the flight ends, the duty ends. What continues after that is your choice, not your obligation. This is not weakness to admit. It is accuracy. A man who cannot set down his post is not more faithful—he is only more tired, and less useful the next time he is needed.
