Congrats on building an excellent financial base at your age, and LBYM. That said, I wholeheartedly agree with other posters concerned about that nest egg being enough to FIRE before age 40 with 2 young kids. Fifty-plus years of life expectancy creates a HUGE cone of uncertainty. Just a few years of high inflation (as we had in late 70's-early '80's, and just a taste of in '22) or a major bear market (sequence of returns risk) can make today's nice sum look pretty small in short order. Health care costs over time (insurance premiums/copays/deductibles/uncovered expenses) can be HUGE, especially you or a dependent develops a chronic illness. Kids college expenses (unless you intend to just cut them off at age 18) will likely total multiple 6-figures (unless they are star athletes). And there is the risk of future tax increases (Fed and state/local) with the Gov't running such large deficits that eventually need to be paid for. Then there is the mental aspect of ER. I REALLY thought I was ready to FIRE with plenty of $$$ (WR 1%, literally) in my 50's, but I failed badly. First 3mo were almost euphoric high, but by 6mo I got back into consulting before taking another FT j#b. Got out (2nd try) 3+yrs ago- hopefully for good this time. Still miss some aspects of my old jobs, but coming to grips with new station in life.
Good luck whatever path you choose!
