I would buy a lot of gold from countries and places, you see, because gold will always retain value, paper dollar bills only last as long as the country lasts.
Then I would use normal dollar bills to pay off my parents home(or buy them a nice house) and all their cars and debts, then use the money to help out people and buy awesome things for myself.
Epic computer(which will suck in less than a year later :D), nice tv, nice apartment(When I'm older), go to college, pay for brothers to go to college, and more that I'll probably think of later but not post for lack of reason.
