My material needs are paltry, so I'm FI with even low financial wherewithal. But unless our current global situation becomes an arrant catastrophe, the personal financial wherewithal should be, knock on wood, OK.
The key point is that I'm not emotionally ready to retire. But neither am I interested in a traditional cubicle job. So, I became a professor. But unlike most tenure-track professors, I'm not sweating getting tenure, because this is an encore career, and further work is optional. If I can last the 6-year period leading up to tenure review, and then get denied, that's OK. I will have by then presumably done some soul-searching, rekindled my various hobbies, and reached a sense that professionally I've done "enough" to justify full retirement, with no disclaimers or asterisks.
What makes it "Barista" in my reckoning is that the pay is lower than what I'd had in my former career, the hours are irregular (by design), and I am competing with people 20+ years younger... that is, normal career-track assistant professors. I'm older than our department chairman and most of the senior faculty, though we do have a smattering of fellows around 80, and a few adjuncts even older than that.
