The article strongly correlates this interpretation of "working" with "being happy". Two quotes:
> When I asked Patrick Collison when he started to find idleness distasteful, he said
>> I think around age 13 or 14. I have a clear memory from around then of sitting in the sitting room, staring outside, and wondering why I was wasting my summer holiday.
And
> Now, when I'm not working hard, alarm bells go off. I can't be sure I'm getting anywhere when I'm working hard, but I can be sure I'm getting nowhere when I'm not, and it feels awful.
My point to the above is: if you feel awful when you don't work hard on a job, by all means work hard on a job.
But if you feel fine only working moderately hard, and that is enough to fund your true passions, pleasures and happiness, do not feel bad for not wanting to work hard on a job.
And the reason I felt the need to say that, is that "hustle culture" [1], which this essay is not far away from in my opinion, might make people believe (incorrectly) that only people who work hard at a job are valuable and worthy human beings.
