I'd put to sea after buying a beautiful tall ship.
quit my job.
(dont tell my boss!)
If I won the lottery, I would buy Bon Jovi, and make them play in my big house on the beach..
Invest, Invest and Invest...
Pay off my student loans, travel the world and go live in Italy! ^^
I would afford a love affair, or better sexual one. Of course my wife doesn't have to know about it:) Having a big money out of nothing is a problem. I read about the case in which a guy wanted to kill his winner-of-lottery brother, because the winner had shared too little of the prise:D if you win don't inform anybody, including your relatives and friends. Heading for a tropical island is a kind of solution.
