The reframing of executive dysfunction as a kind of mental inertia is interesting and consistent with my personal experience with the phenomenon. They say that the beginning is the hardest part, but it has always been almost unbearably hard for me. On the other hand, once I start doing the thing I wanted-but-wouldn't, I usually go on with it for quite some time.
This also reminded me of the article[1] about the “Bayesian interpretation” of Autism and several others mental conditions. I'm not sure how much rigorous study there is behind such theories, but they do provide an interesting framework to think about these conditions.
