Yeah, there is just too much Tony Robbins referring to cells living of light in some jar linked directly to your work productivity (and thousands of other debunked BS "facts"). The levels of coaches for coaches for coaches for coaches on LinkedIn is approaching levels that shouldn't even be possible. I feel like almost everything about this topic has been said, but the amount of things being said is increasing exponentially, and it's all coming out of thin air. Like an LLM expanding the current body of work.
I for one used to enjoy such books but have turned more to mind-fuck scifi (i.e. I keep hunting for the Ted Chiang level books, although they are also very rare). I find meaning in those.
