| Ha. I joined the Navy in the 90s and when I got out I tried to get into auto mechanic school. They wanted me to sign up for an apprenticeship at a car dealership and were happy to take my tuition money. But no one would allow me (female) to apprentice. They would say "sure...wait a bit for a start date" then I would call to ask when to come in and they would always have given the spot to a male student. Even after getting into the IT field, I tried to learn carpentry. I went to local shops that had the tools. No one was receptive to me for some reason. They were either closed during the times I could go after work, or defunct, or only wanted people who already knew carpentry (WTF). Anyway, I entered software development because it was the only field that would hire me entry level. Aaaaaandd the only field I could actually self-teach. I am grateful for that fact...that you can teach yourself through books (back then no StackOverflow haha) nor Youtube, nor Udemy, etc. Just plain push yourself through the text books available. I spent a LOT of time at Borders books and Barnes and Noble, trying to figure things out. You can't really do that with carpentry. Maybe you can self-teach auto repair. But as a woman, not even my family members would spend time to teach me (I had a cousin that was embarrassed to have me help out at his auto shop). I got away with self-teaching IT as a black woman because it is not nearly as sexist or racist as other fields, with Indian and other immigrants showing the way to enlightenment to a great degree (in my personal experience). |
But then if you watch channels like Essential Craftsman it's clear there's a great deal of know-how that has to be passed on by someone who knows the trade. Stuff about how to work efficiently and tricks you wouldn't think of. Even if it were in a book or videos exist, you don't necessarily know to go looking for it.
It is definitely possible to self-teach auto repair. I did, out of necessity. Things you try either work or they don't, but there's logical reasons for it that can be derived from first principles.
However the computer is in a class of its own when it comes to self-teaching. Instant feedback and infinite capacity for experimentation. Carpentry doesn't have a built-in objective critic like that. Auto-repair is somewhere in between.
