Build my mother the house she want's with WHAT EVER she wants in it and on it, and hire people to take care of it for her. Buy my 84 year old friend a new car and pay the insurance and up keep and pay her DR bills so she can get the meds she needs. Hire someone to care for my handicapped spouse. Buy a BUNCH of purses. Go on a long trip to Alaska. Then I would take a breather and hibernate a while and decide what to do next.

Edited to add that it is gonna be pretty hard for me to win the lottery as I don't buy tickets.
