Okay, pencil me in for May-ish. :)
We hit a theoretical FI number a year ago, but we have a baroque plan that might call for some extra buffer in ways that aren't obvious how to reason about. We're expecting to stay in an HCOL area (silicon valley) until our youngest is through the local school system (which locals know leaks a lot of info about how very high H. the C.O.L. is here). FIRE isn't viable if we're living here forever, but cFireCalc gives it high marks even with a downsizing 14 years out. This model values our home as tracking inflation in the interim, but not appreciating beyond where it is now. Still: feels prone to historical accidents around how two timing points (FIRE + downsize) align w/ historical economic performance. So: OMY, at least. (Check.)
Since then, DW called it quits at work to homeschool the oldest. (Public school wasn't working well for him. Homeschooling's going great though.) Work said "how about a leave of absence for a year instead and then see how things are going?" That's no-lose for her, so that's what she's doing. She likes a lot of what she does there, so she might go back on a dramatically reduced schedule retaining the low-stress stuff.
Meanwhile, I had been churning away at some really interesting challenges at work that have since reached their natural conclusions. It's a good time to turn the page. Two things holding me back, for now. First is economic. On 1/1, marginal tax rate drops down to zero temporarily. Also, a bunch of benefits reset, most notably the generous pretax 401(k) match that I can frontload. Second is lifestyle: daily bike commutes, free tasty protein at work, and job responsibilities that are fairly chill right now. We're FI, but not so loaded or confident that I want to pass on money earned that efficiently.
Lots could change, but I think the overwhelming likelihood is I pull the trigger next year.
