....that video is now going to be my response to anything I find to be extremely confusing or nonsensical, or just idiotic.
Anyway, on the note of school.... there really isnt much you can do about it.
I think the worst part of it is teachers always trying to convince the students that yes, they need such-and-such subject later in life! You cant do without it! You've gotta know this stuff!
In my experience, that's a big load of crap. I knew full darn well that 95% of the crap they were trying to get me to pay attention to was bloody useless. Even when their reasoning almost made sense: "Well you're into computers, right? You gotta know all this math stuff for that!". Nope. When programming I just figure out by pure logic... not by having memorized mathematical formulas... what needs to go where in order to get the thing to do what I want, which works out well because it's the computer that actually SOLVES the blasted equations; I just need to figure out what I need it to solve. And of course that's not even speaking of all the other junk like history or literature or worse, things like "shop" class (I dunno if that's what they call it now) which was pointlessly learning to make things out of, I dunno, wood or whatever. The vast majority of all of that stuff was and is and always will be useless to me. The ONE major thing I learned in high school is how to type properly. That's IT. Everything else? Useless. All of the stuff I DO know now, I learned on my own, and the school would have proved incapable of teaching it to me. Computers and programming and that sort of thing for example. The computer-related classes were always really basic level stuff, things that were utterly mindless to me. I'd started programming around age 7 or 8, and this was back in the days of DOS, before Windows was even a thing. I knew how to use the stupid machines. Pointing this out, though, would accomplish nothing, they'd still want to "make sure you know the basics", which... makes no sense. And my love of books and reading didnt come from literature classes or whatever, I got into that on my own.
And that's the whole problem with the school system, I think. They dont actually KNOW quite what to teach to different groups of students, so they just throw absolutely everything into a blender and just hope it accomplishes something, and hope that they dont look like idiots in the process.
Aint anything you can do about it except put up with it, unfortunately. The really irritating part is that much of the time, even colleges will make you do this unnecessary crap even when your focus is very clearly elsewhere.
