The part about retirement is total BS. I worked hard to FIRE in my mid 50s as I had already over 300 books still to read by then, min 20 countries I still wanted to visit, two additional languages to learn enough to be able to read in original some of the books not having been translated in the languages I already know, and update my physics and math college knowledge from when I was younger. None of this was possible while working. And quite a few years later I now have over 500 books left (the original ones had tons of references which expanded a lot of books to a few more), still places to see, even in countries which I crossed out from the original list, but I could not completely traverse, or languages not yet mastered to the level I need.
