An old fighter pilot saying goes “It is better to die than to look bad, but it is possible to do both.”
While I don’t agree with it, there is a bit of truth to that quote. Many of us have a bias where we don’t want to look bad. It’s the reason we take pride in our landings. It’s why we don’t want someone to climb through us in a thermal. It’s why we don’t want to come in last. It’s why we continue a takeoff rather than abort on a contest day when you’re number 3 to launch and there are 30 gliders behind you.
“I don’t want to look bad” says the voice in our head, and more often than not...we listen.
