Yeah, Meh.
She hated her job (didn't say what it was), went the FIRE route for a bit, realized she was more miserable than just the job, backed off from FIRE, and find "meaningful" work (also didn't say what it was). Big on headline, short on details. FIRE should make liking yourself an easier project to tackle, not a harder one.
I mean sure, there are plenty of jobs I'd rather have. Heck I like a lot about he job I have despite it not being terribly "meaningful" (I make the chips that go in the gear that tests the chips that go in your cell phone...). I still would rather spend more time with my kid and more time adventuring than any full time job will ever reasonably allow. I also am just tired of all the life wasting administrivia that come with a corporate job. Annual reviews are going through their motions right now, which is always a low point to the year, and we have to jump through the hoops despite there being zero raises this year. I'd rather be FIRE'ed and be sewing, hiking, biking, running, and sleeping in, clearly she hadn't figured out how to have a life outside work, while my life is neglected because of work.
