Create my own drug empire - gets you a lot of money but needs a lot to start. Hahah messing! Buy about 10 - 20 houses each at around 100 - 200K, Rent them get more money, Buy computers and random modern shit I would never have thought about buying, Quit my job (If i had one) and travel every place in the world.
When I die pass the houses on easy money for my children/grandchildren (If i had any) to start their own buisness/live a happy life
