CYA
Simplify Tail Risk Strategy ETF

Maybe it's me being extra, but whatever you think you need, I think you should add a other 25%-50% to it to CYA before retiring.
It's one thing to downgrade your income and take a less stressful job or something (sounds like that doesn't really apply here), but to go from 300k a year income to nothing, and only getting a third of that income from your investments? That's a lot of risk.
Besides that, inflation keeps coming and compounding, so you need to be able to reinvest enough to offset that. And then I suspect that with this newfound time in the schedule, you'll find stuff you want to spend money on that isn't accounted for in the budget currently.
Of course, it's possible that none of these apply to you, and if so feel free to ignore me, but I'd aim for extra, especially because I have expensive taste.

I’m playing it this way with warrants to CYA (CMA?) in case I’m wrong.  If we go parabolic I’ll fine with 10k warrants.
