Split up a lot of it to family and close friends with agreements on what the money would be going to. I would want to know that I would be helping them buy a new house, put kids through college, paying off debt, etc. Obviously people really close to me would get more and have more freedom.
Then I would buy a huge amount of land and build a major complex that would include state of the art security, underground bunkers, multiple buildings and or houses, a dragstrip and or road course, probably a helicopter, shooting ranges, etc.
Save the rest and retire at 23.
