Anecdote: I have ADHD (diagnosed) and I think I can safely say that it is the single highest source of stress in my life.
Interest-oriented motivation is incompatible with employers’ needs for predictability. I’ve lost entire workdays because of completely irrelevant side-quests.
I find working on a contract basis is much more compatible with my ADHD experience than being a FTE because I can at avoid charging for days when my brain goes completely off the rails.
This is with medication and years of psycho and occupational therapy. This is with regular exercise (which definitely helps). I think I am managing the disorder with the best tools I can reasonably get my hands on right now and the best it ever gets for me is controlled chaos.
I do love the rush of learning something new that folks with the disorder tend to get but, man, at this point I would happily ditch that occasional good experience in exchange for behaviors that look like a functioning adult in his 40s.
