What would you do with it? I am talking about one of those outrageous lottos the 400 million jackpots. I know I would pay off a whole lot of things first and foremost. Then give immediate family and friends money. From there I would get a house and continue my schooling. Not sure I would buy one of those obscenely huge mansions that celebrities have. I see no reason to have a house that big. Not unless you are renting them out like a hotel.
