MMR updates are superficial. Weak signal. I'm confident most are absent of critical info and some are entirely made up. I don't disbelieve anyone in particular, but when a mechanism of virality proliferates, it often gets deployed without the backing substance.
"How I XYZ" around money is similarly misleading. Most entrepreneurs I know cannot recreate their own success – when they set out on a new venture, they need to look with fresh eyes, invent some new techniques, and discard a lot of methods that previously worked. If entrepreneurs aren't even able to reuse their own "how I xyz," then how will a stranger with even less nuance be able to learn or apply much from the blog post? Again, some of these stories have great lessons, but as a category I believe they are more noise than signal.
Finally, the sheer obsession with money saddens me. The great entrepreneurs of our world are hardly motivated by money – to them, money is a tool that they factor in as they work to realize a vision, not an end goal. How ethically/morally impoverished is this technical class to be so obsessed with money? There's a term for this – greed. I know that a lot of jobs suck, a lot of stuff in life is expensive, we need money to do a lot of basic things, etcetera. But money is not the only solution, and more money is not an even better solution. I don't think this incessant messaging around money is virtuous – I think it is both a product of greed and a means of harnessing the greed in others. (And where are the entrepreneurs bragging about impact?)
(For the record, I am not jealous – I make my money doing literally whatever I want, on projects that I find much more exciting, with ample time left over for nature walks, rock climbing, reading, and more. Unlike these authors, the money I make is not the most interesting part of my story.)
