Doesn’t have to be a thing you bought. Just some thing you didn’t have but then once you did it expanded your scope of actions.
The first obvious example that comes to mind is a car. Plenty of drawbacks to prevalence of cars, but being able to go where I want when I want, and far away, is very transformative.
I’m interested in other examples of things that aren’t just useful, but that open new possibilities.
We’re not rational, but there are patterns. If you’re willing to do some reading Thinking: Fast and Slow is beefy, but helps to show some of the patterns of irrationality in a structured way, from one of the leading experts on human behavior. If that’s too much, Thinking in Bets is a nice taster that still is well backed by much of the same research, but is shorter and more accessible.
Interesting… time to dive into those books.
