I think the danger is not just unrealistic expectations from a point of view of "I'm just not that much of a genius/producer", but (not necessarily article-related) I think it's important to realize how unusual the story is of the "super successful" and "driven" people we so often compare ourselves to.

Now that I'm older, I realize that where I am is not surprising despite the work I've put in; what would have been far more unexpected would be for everything to have worked out and grown so large that I'd be one of the big successes.

That measuring stick would need to be configured against the mean, assuming it's needed at all (and it likely isn't).
