This seems correct, and I suffer from the same issue as the author, but I'm curious if it's as simple as "you don't believe in the projects". Does Pieter Levels believe in all of his projects so much that they burn a hole in his brain, or does he just think "this seems like a good idea, I should do it and see if it works" and that's enough to get him to the finish line. I assume the latter, but it's just a guess.
I'm not familiar with his work but from a quick search it seems that he's a hustler and is very "eye on the prize." I would think that your characterization of his process is too blasé and that there's actually more conviction behind it, but of course I don't know either. Most of the time I would say that prolific people that seemingly casually whip things up have learned to affect that and there's usually a great deal of obsessiveness happening behind the scenes.
Also, I don't much like the framing of "you don't believe in the projects." It's not meant to be a fault of the person, and I'm sure Pieter and others have graveyards of half-baked projects (which may even be revived one day) - it's part of the process - but I just mean to say that you haven't yet hit on the idea that keeps you up at night (or some nights at least) until it's been realized.
