Having anything at all near me that supplies instant gratification (electronics, mainly) puts me in what I call "hunted mode". That is, I'm itching for something to switch my attention to and very easily distracted. When I remove such things and engage with the world (and turn off or DND my devices -- important) then I seem to enter "hunter mode" where I can put my focus where it needs to be and hold it.
So, of course I become a professional software developer, right?
Adderall lets me work. Turning shit off when I get home lets me live. Paper books let me read (ebooks for reference, though; I'm not a Luddite).
Which is to say: I'm with ya, and you're right about environmental sensory stimulants. But you're kind of wrong about it being a matter of self control. It is, but the problem is that you (we) lack the control of self-control. That's the nasty thing the article doesn't go into. This is an Executive Function disorder, a "cousin" disorder to things on the Autism scale (ever read a list of those symptoms and check off an uncomfortable few?). That's why we wind up medicated. We do need that dopamine to hang around to push through the daily administrivia.
Yet, the article was right that outside of city life this would be great. But I'm a city guy, so ... yeah.
