Buy a small handfull of solid, and profitable law and accountancy firms, perhaps a security /private investigation firm to go with it, no doubt some property, investment accounts and more solid investments-and Miss Emma Peel as my personal assistant.
I would spend $40 million of houses cars and the things that I want to survive. The other $60 million I would invest to grow exponentially.
I guess I would buy a small soccer or other sport team and try to make it into the higher leagues over the years.. with 100 millions you can make a lot of damage in the sports world i guess .. so i can stop working and still wont get bored.. with the rest of the money i would buy lot of silly stuff for all my friends.. and then destroy them again gg
