Given my track record with lottery tickets(it is big news if I match ONE number)it is a moot point, but I would make sure that I couldn’t spend it in large chunks without considerable effort before I claimed my winnings. I know that I would spend more of it than I thought I could, so I would probably give myself an allowance for buying certain stuff like a boat and tow vehicle, buy some land and a few things that go bang, but leave most of the money relatively untouchable and live on the interest. I would also set up a charitable trust and use that for tax deductible giving. Otherwise, I would go Galt and have as small of a government footprint as possible and limit my exposure to scammers and moochers.
