I have advice for the wanna be winner....reread Steinbecks novel The Pearl. As soon as you are in possession of the money you are a target of envy and scorn. All that you have accomplished financially in your life is immediately null and void. Your children and your wife are now targets of kidnapping. No thanks. Rather spend the money on a good cup of coffee.
This would be the biggest worry. Physical harm to you or people you care about. A few states allow people to claim anonymously. Just a few though.
With that said, I spent $5 on three pieces of very expensive toilet paper today. Two tickets for 1.6 billion lottery and 1 ticket on some state drawing. That's my lotto purchases for the year except for the money spent through a work pool which I don't put any effort into.
