I would buy a bookstore, some bars of milka choc, go out for coffee, hire a bodyguard, buy some clothes, get an iphone & ipad and an iwhatever, buy saffron. Go on a holiday (a very long holiday) seeing all the places I've ever wanted to visit, alaska, egypt, china, japan... you get the idea. Buy a nicer island than the one arista is gonna buy, buy a house in canada, an apartment in new york, and this
Chambord Castle of Paris
I would also start a scholarship, that allows people from poor families to goto university, as many as I could afford.
