I'm not sure what this talk about luck and privilege has much to do with the core ideas of the article, which I took to be:

* look critically at your life's successes and your interests, discern what to prioritize

* being aware of societal abstractions and what you're "supposed" to do in life affecting your choices

* that your current "vision" of a proper life might not be the actual best fit for you, precisely because of the above abstractions

I thought these were generally fair points, if not rephrasings of common wisdom like "iterate more" and "your first idea isn't perfect" and "be wary of preconceptions". If you're in a bad material situation, I'm not sure that everything here suddenly doesn't apply?

Not saying that the author isn't privileged, that the path to success wasn't made easier by being able to travel, rent, and buy a farm in the footnotes. But again, the advice seems to be pretty universally put no matter how big or small your steps are.
