People didn’t care about this rational math. People, in general, are terrible at valuing their time, perhaps because for most people monetary compensation for one’s time is so detached from the event of spending one’s time. Most time we spend isn’t like deliberate practice, with immediate feedback.
Wealthy people tend to receive a much more direct and immediate payoff for their time which is why they tend to be better about valuing it. This is why the first thing that most ultra-wealthy people I know do upon becoming ultra-wealthy is to hire a driver and start to fly private. For most normal people, the opportunity cost of their time is far more difficult to ascertain moment to moment.
You can’t imagine what a relief it is to have a single overarching obstacle to focus on as a product person. It’s the same for anyone trying to solve a problem. Half the comfort of diets that promise huge weight loss in exchange for cutting out sugar or carbs or whatever is feeling like there’s a really simple solution or answer to a hitherto intractable, multi-dimensional problem.
