I would hope I never won the lottery. To take reign over that amount of money, for real lottery winners, is after some time of a) dreaming up what they would do, like this thread, in fantasy land and b) a life lived within much more meager means prior to winning. This is the best scenario ever, winning a lot of money, for all the bad sides of human nature to show themselves.
Most I've read about ended up in more debt 10 years later, some divorced, some dead, families torn apart, friendships lost, drug addictions, gambling, greed, gluttony, etc...
I sound like a priest, but the philosophical implications of having that much money, money which is thought of as power and the ultimate objective of a lottery player's life, is like giving the role of Caesar to a peasant. An uninformed, illogical, emotionally driven, nearsighted peasant. The lottery is a curse, lol.
...but if I was to be handed a winning lottery ticket, I would invest it / donate it / gift it to others who needed it - ideally. I am sure I would fall victim to some material desire or another, as would anyone.
