My wife has mentioned I probably am on the spectrum, and/or have ADHD/ADD (she is diagnosed with ADD). I have many of the same “symptoms” as you; mechanically inclined, love electronics, terrible at social situations/reading facial expressions, science was my favorite subject in school, math was my least favorite though, I still count on my fingersbut I can do the trig required for being a machinist no problem… except I absolutely loved reading.
In 6th grade and forward we were required to take Lexile tests, which measures your reading level, I was reading at a college freshman/sophomore level. In high school I read a 7 book series (~130-200 pages per book) in 5 days, the librarian didn’t believe I was actually reading the books so she tested me on them before she’d let me check out another. After that she’s let me check out 4-5 books at a time so I didn’t have to keep going into the lib
My biggest problem is… motivation I guess you’d call it? If I don’t want to do/learn something, it is almost impossible to being myself to do it, and I wish I wasn’t like that but I don’t know how to bring myself out of that “this sucks, I’m not doing it” mentality. But if I want to do something, nothing else matters, that thing is getting done right now. That has caused some friction between my wife and I, she’ll say something and I’ll start looking it up immediately/go to find the object she’s looking for and she’ll be like “can’t it wait, we’re talking!” I’ve gotten better, but she says I’ll start “vibrating” because I need to know that piece of information/get the thing and it’s clearly bothering me lol.
My organization skills though… best described as “loosely controlled chaos.” I know where my stuff is, but to anybody else it looks like I just put it down and forgot about it. But please don’t move it even a foot because then it’s gone forever and I’ll spend 30 minutes looking for it.
