I would set up my family to be well taken care of and whatever was left over ... I would set up some kind of organization to help people.. a charity of sorts. Not clear what... but every time I see people on the side of the road or sleeping under a bridge or pushing a cart that has all their worldy possessions... I want to do something about it.
I would quit my job and do that.

Of course this doesn't mean I wouldn't buy fast cars and boats and blah blah blah... but there has to be some kind of balance.
And not winning the lottery shouldn't stop me from helping people as I can.... but that lottery should be more-faster!
