"Do I look like a cat to you boy? Am I jumpin' around all nimbly bimbly from tree to tree? Am I drinking milk from a saucer? DO YOU SEE ME EATING MICE?" – Trooper Foster, Super Troopers
Sometimes you just have to laugh. That's a quote, too, from The Wonderpets. If you take yourself too seriously, you won't be much fun to be around. But laughter has many other benefits, one of which is the ability to improve your outlook and increase your positivity. At some point when things are pretty bad and you have a moment to yourself, reflect on something you find funny about the situation. And it should go without saying that I stress "to yourself" because when things get pretty bad, sometimes the attempt at humor isn't shared.
However, having a smile to yourself, even in private, works wonders. And like Springsteen once said, "Someday we will look back and it will all seem funny". Note that he specifically didn't say it would "be" funny. Seeing even some dark humor in a bad event can sometimes at least help you cope. And in our business, being able to cope means that you can live for another day.
Keep it together and watch out for one another. Stay safe during this holiday season. And find time to laugh.
