No kidding, part six literally opens with:
> I do not believe ADHD is an inherent thing.
They just put those cards right on the table, lol. No hesitation!
What I think a lot of people don't realize is that ADHD is classified as a neurodevelopmental disorder alongside stuff like autism. Which means attention and executive function are only a piece of the larger puzzle; ADHD's biggest impacts on me as a kid were (1) difficulty regulating emotions and (2) general social stunted-ness. I still struggle with the former, I thankfully caught up on the latter (mostly :P), and "attention" issues have remained an undercurrent throughout.
Various medications, and not just stimulants(!) have helped on all fronts.
