I'd learn my way around investments and all that jazz. Make massive interest for a year, then start dishing out 100k to each family member/friend who has earned it (that makes for about 4 family members, and two friends. ).
After that, keep investing right and living off the interest.
Everything from there on in would be fun and games. New comp build every 6-8 months, nice car (which for me wouldn't even be expensive).
In line with a house, dunno if I'd bother. If I did though, it'd be fully decked out for tech, server closet, future proofed (got ideas for making future tech easier to implement), wireless-friendly, LAN-room(s).
I called 5 local banks and figured the average interest rate on their cd's.. If i depositted 1 million and left it there untouched for 1 month. i could then spend 4K per week every week for the rest of my life without ever touching that 1 million.
id buy a nice new pc and laptop and a semi good car and save 20-30% of the cash for the insurence or something like that then id buy myself my own place prolly a apartment because i like small spaces untill i need to buy a house and what ever is left over i will invest and get a job to add to it then if i get fired or something i can fall back on a huge wad of cash and be allright
At some point though you have to look at each and go...hmm the gumpert has a terrible name, and is terrible looking. The Ascari on the other hand is amazing looking. And the sound it makes!? Worth buying just to listen to it.
