> Why would a huge chunk of the population have a imbalance of brain chemicals?
That's what I think about from time to time as well. I have ADD and take meds for it. But I'm pretty sure that I only need these meds to be able to work in an open-space, corporate IT environment with dead-lines, responsibilities etc.
Without meds I get overwhelmed and panicky quickly, when taking them they turn me into kind of an office robot who's able to work without getting too stressed out or distracted by other things.
I suspect that I wouldn't need the meds if I had a different job. Which feels weird, because it sounds like I'm trying to fit into an environment, instead of being in an environment which fits me, if that makes sense. Then again, maybe everyone has to do that and it's just my biased perspective that I'm the one who's not made for it.
Which sucks, because I love IT, also as a hobby.
The easiest examples for that: Sometimes I do an IT project at home, maybe build a PC, configure a homelab, try out Stable Diffusion or edit videos from time to time. If I do these things at home I can easily sit in front of the computer for 5+ hours and loose track of time, but I don't seem to be able to be as focused for IT projects at work if I'm unmedicated. Unless they really interest me.
