I would put about 10 million in savings across multiple banks (I am guaranteed a return of $200,000 if the bank fails so I would lose $9,800,000 if I put it all in one bank and it went out of biz, also makes it harder to steal).
I would buy SoCa Studios, Ace of Spades = Mine xD
Pay off all my families debts.
Then buy a nice house, computer and invest some money in the stock market. Try to stay low on the radar. Live comfortably for the rest of my life.
I would still work and stuff, but atleast it wouldn't worry me to be unemployed and I could have a nice house no matter how much I get payed.
