I think time helps shape perspectives here.
It can be really hard to tell someone's career or life trajectory in the moment or even in 1, 2, or 5 years.
I'm 35 now so I have the benefit of hindsight looking back on the decisions different people my age have made and while I'd be the first to caution against potential bias in data I can say definitively that the people who were into FIRE or grindset or whatever before those terms even existed have ended up markedly worse off by their own definition of success than people who took more traditional routes.
There are exceptions, I know one person who made millions on cryptocurrency for example. But he's the one exception to the rule I can think of.
The rest ended up no better off than their peers who weren't out there posting every motivational quote on social media or eliminating their social lives to write and ebook about credit card reward points.
So was it worth it? I doubt it. The ROI seems to be negligible or even negative to me.
It turns out there was no shortcut to wealth and happiness after all.
