You can summarize any “self-help” books which I read in single pages. And most of them even in a few sentences without loosing any information from them.

One of the first which I’ve ever read fully was Getting Things Done after a Lifehacker article eons ago. The book had zero additional information compared to the article. Back then I didn’t know that these books information density was almost zero, and still is.

Last year I bought a book about eating well. I could read only the first half, because it repeated until then basically a single mantra: eat fermented and macronutrient rich food. This was repeated different ways, without adding anything to this summary. Sometimes literally the same sentences. Reasons were not provided, or was on the level “I knew somebody whom this helped”, without even trying to convince me that it was really this what helped them, and not anything else.

The dietary guidelines from the US is a way better read, and that’s free. Even the current, clearly politically distorted one.

Maybe, that’s the main reason. Free information is better or at least good enough. I haven’t learned anything from these kinds of books which was not available freely (and legally… because you can obviously get almost any books illegally).

This is a brilliant summary. I recall following Michael Lynch's journey while he built TinyPilot (https://tinypilotkvm.com/). I was blown away by how hard he grinded to build that business. It just never let up -- the competition. As successful as he was, the exit value seemed like a let down (I say that as a fan!). So, I agree: "Draw circle" by far the hardest part. For "rest of owl", just hire other (grind-ier/thirst-ier) people to do it for you!

Perhaps, but them how do you explain the claimed pattern that sales had been unusually consistent until just recently?
