Author here! Thanks for all the comments. This post isn't meant as a lesson or a judgment, something to tell "just shut up and adapt like my ancestor did". The situation is hard, and I wasn't trying to dismiss anyone's anxiety. No one wants to hear "you'll be fine" when something bad just happened.
It's mostly a personal story. You can see it as a kind of tribute to a great-great-grandfather I never met, partly because I'd never heard a story like it before. It's banal but still a big adventure in the family. I find it fascinating that he grew up in a completely different world from mine and still felt some of the same doubts and anxieties I do today. And I'm really proud of him, because his "pivot" let my family stay in the village instead of maybe leaving to work in factories in the city. My father loved his job, and in a way that's thanks to him.
The flagging here is better than in a Steinberger thread. Unreal and congrats.
Sounds amazing. How on earth did he go from shoeing horses to learning about the internal combustion engine? Seems quite the leap that not everyone would be capable of.
