Why don't you quit your (assumed comfy US tech) job and go retire in a low cost-of-living area? I know that it's not the same thing, but the answer might be similar.
Truth is though - if I could ever achieve a payout of a few million or more, I'd call it a day, right on the fucking spot. Invest in long stocks and dividend stocks, and go live in a small home near a cold weather city. I grew up around billionaires, and they scare the shit out of me...no intention of becoming one.
