I'd probably have to get cosmetic surgery to remove the smile off my face!

I'd spend some, save some, invest some, give some away etc., and use it to make my life and the lives of others better.
I'd also set up a foundation in the name of a friend whose lifelong goal was to set up this type of a foundation, but will sadly be unable to do so.
