Wow, I think Sunsetbeach has the right idea. Give first, then take care of your needs/wants. This may sound crazy, but I think that insane amount of money could actually ruin a person's life (I know, many want to sign up to see just how out of control things can get).
I think there are many things I would do like buy a huge acerage out in the middle of nowhere with a nice house with of course, horses and cows. Take care of some family for sure, but also I would seek out families that are in desperate need of financial assistance. I know I would get the most satisfaction out of helping them, and knowing that I made a huge difference in their life.
