You’re right… it does go a lot deeper. If you’re in the USA, your local community college might have classes. Consider starting with some formal instruction. The problem with YouTube is that you (the one lacking knowledge) has to decide whether the YouTuber knows what they’re doing. There’s a lot of great stuff on YouTube, but there’s plenty of wrong and unsafe stuff too.

Also, avoid super cheap tools for the tools that interface with screws, nuts, and bolts, like wrenches, sockets, screwdrivers, hex and torx drivers. Cheap tools make it wasier to damage screw heads and bolts.

Training courses and apprenticeships; there are a lot of specialized tools, techniques, and diagnostic procedures that aren’t obvious. Self guided usually results in doing a lot of things the wrong way.

Asking you to provide evidence in support of a position they’d never consider distracts you and keeps you busy doing worthless things.

And yet… I would’t bat an eye if I saw a new executive order tomorrow requiring that.
