Why did I get the downvote? I want to know because this is the approach I took, and I genuinely hope that sharing it can benefit others. Yet I sense my suggestion may not be as helpful as I'd like it to be, and welcome ideas and improvements. My guesses as to potential causes: 1) I suggest committing crimes to get learning materials 2) I suggest very hard work / very difficult topics, right out of the gate, instead of hobby grade projects 3) self teaching this stuff might be an iffy prospect 4) self teaching /while winning and executing contracts/ could require a decade of pre-existing manufacturing experience 5) I didn't lead with ERPs Yes, I am being somewhat snarky. However I genuinely welcome insight here. I want to become a better mentor for people like myself, and potentially OP, who are blazing the hard trail of non-standard careers in manufacturing.
