I've thought about this a lot. I'd probably try to give/donate most of it away. I would keep enough to keep the family tree in great shape for a few generations, but otherwise all that money is a curse (in my opinion). Spend the money to help people by donating to organizations that are valid and respectable. Help the poor, help the sick. Try to do as much good in the world, or even just your neighborhood as possible. Not many people have complained out loud that a person is doing too much good, helping too many people.
