You can just skip the clearly marked ad bit and read the rest of it. Jason Pargin makes a lot of good content on different channels, and throws in a book plug here and there. Doesn't diminish the quality of his writing in any way.
The rest of it sure does read like "content", yep. There's no substance. It's short. And then there's another book ad.
It reads like someone used an LLM to cough up an article as an excuse to show the book ads. Though I don't actually think it's LLM-generated, mostly just because of the unnecessary ALL-CAPS in the middle, and the overuse of bold, italics, and underlining throughout.
