I have a print out of this on my wall. I also have pretty bad ADHD. It's been on my wall a year and I still haven't done the thing (really a series of small aversive, timeliness and administration heavy things). I oscillate between trying to do the thing, and trying to treat ADHD or at least not regress (sleep (difficult), exercise, nutrition, intoxicants socially only, stay away from digital dopamine sinks (really hard)). Then I have a burst of panic that trying to improve executive function is itself not doing the thing.
