I would
1. buy an island that has a dope skate park, zoo, giant house, and its own ozone that allows me to regulate the weather.
2. buy one of those dream machines from inception so i can do stuff when i sleep.
3. bring everyone i like to my island.
4. pay Jet Lee to assassinate everyone i don't like.
5. buy Misa Campo
then do whatever i feel like doing because I'm rich.
