Just because he does not articulate that "I have health problems, thus a normal job does not work for me" does not mean that isn't baked into his choices. He was apparently relieved when he was fired because the job wasn't really working for him.

The lack of that observation may mean he isn't the most stellar author ever. Or it may mean he is not some font of wisdom and his explanations are sort of half-baked. But none of that is evidence that his choices were irrational.

It doesn't have to be the same choice you would make for it to be rational.

And I don't owe you justification for my life choices. It is obnoxious to imply that I do.

I haven't dismissed nor attacked your life choices. I have merely pointed out the obvious-on-the-face-of-it fact that your life is different from his and this creates different decision trees and different outcomes. That's it.
