I kind of wind up being in the clear with electrical stuff right now, since one of my stepsons is very good at that, does electrical-adjacent work for a living, carries all the necessary tools at all times, and just loves to show you what he can do. I don't even have to ask him for something, I just mention that there's something going on I'd like to get done and 5 minutes later he's waist deep in it, like a 5 year old saying "look at what I can do!"
I can do a little bit of carpentry without youtube, but really I feel like the end of the line for the two sides of my families. My maternal grandfather was a railroad man by trade, but a jack-of-all trades by hobby and learning. The man could do literally anything, and built the house my grandmother still lives in back in the 40's all himself. And all the upkeep and remodeling through the years, of course. Brilliant woodworker too...he made some really nice chests, bookcases, toys, gift-type items, etc. in his day. He was a very patient guy and loved to teach me things, but unfortunately he passed at 65 and I didn't get many years with him. My dad and one of my uncles are both ace carpenters, another uncle is a great mechanic, but all of them will basically get the job done when it comes to something that's not their forte, like plumbing or electrical. My dad is not a patient man or much of a teacher, and I didn't pick up much of what he knows.
YouTube is a great resource, and I've used it a ton, but also there are some things that in the real world you have to be careful for at times or you'll cost yourself a ton of time and money, or worse, a safety hazard, and I'd still rather somebody help me who knows what they're doing for some things. I have a bunch of physical problems that prevent me from doing an awful lot, but what little I can still do, I'm slowly trying to build my tool arsenal up because I live away from my dad now, and I can't raid his workshop just any old time like I used to.
