At face value it's an easy enough concept, but once you start to think about it, there are a lot of uncomfortable things that come with winning (and some questions).
So basically, if I win, I retire today - never having to work a day in my life. Great! Except my retirement goal is to continue to pick up gigs and odd jobs here and there to keep myself occupied, so that suddenly is out of the question unless I work for free. I also can't jump into an organization (helping friends with a business, lending technical expertise) unless I'm doing it completely out of the kindness of my heart. To never be handed a single penny for the rest of my life because of any work I did would be...difficult to explain.
Also, though I can't work, can my soldiers? If not, inflation would absolutely ruin everything. And if they can? Easy opportunity to set yourself up later on down the road.
What about selling my possessions? Am I to donate or discard everything I no longer want or need?
What about my wife/kids - are they still able to earn an income or is this a family based thing?
Ha, these are the questions I'd need clarified before I could formulate a response.
Supposing three strikes on my questions, I'd probably pick some number that's at least 2-3x my current annual expenses and sock all extra cash for later-in-life expenses, just so that I could maybe net out on inflation.
But if any or all of the three are fine, I'd pick some number that's marginally higher than my current annual expenses and then send my wife out the door as I don the SAHD hat.
