As James Herriot recorded in one of his books, "there's more to be learned with your hand up a cow's arse than in any textbook," which probably makes more sense if you know that Herriot was a veterinarian.Hands on helps.
Or, as the sign hanging in the back of my high school chemistry classroom put it,

There's a baseline of knowledge that you need, which a lot of us got from holding the flashlight for Dad, but when that's not an option, YouTube can be a pretty solid replacement. The thing I like about FordTechMakuloco's channel ( https://www.youtube.com/@FordTechMakuloco ) is that not only is he good at explaining things, but he's also good about listing parts, tools, and specifications in the descriptions under his videos. Those are super valuable when it comes to putting that theory into practice, and putting it into practice is what it's all about. That's when the real "ah-ha!" moments happen.
