What do you do with it? Not taxed the 20 Mill is yours in its entirety. I would immediately donate 5 Million to charitys of my choice. Invest 7 Million and live off whatever it accumulates for the remainder of my life. Keep 1 million to buy a house, car, boat, etc. Outright, + have a little fun. Give 3 Million to my parents, and my brother & his wife. They're far more successful than I am, my bro already lives the life. I'd be extremely embarrassed to suddenly live more comfortably than him simply because I got lucky, when hes worked his ass off as has his wife to get where they are. Same with my parents. So I'd definitely share the wealth with them big time. That leaves me with 1 Million. I would divide it up between my closest friends evenly. I would have a meeting with them beforehand though, making sure they know thats it, the rest of the money has been invested/donated/given to family, and I would not hand anymore out so spend it wisely, in hopes it wouldn't ruin relationships. And hey, if it did, at least I'd know they weren't really good friends to begin with. What would you do?
