I am going to, by priority:
-Pay off my debt.
-Split the winnings four ways between the kids, their mother, and myself.
-Set up trust funds to pay fo the kids, and all of my nephews and nieces colleges.
-Fix up my frined Jays house.
-Help out my friend Mark with his debt load.
-Buy my own house with a pool and a workshop.
-Match whatever I pay for a new car with a donation to the Wounded Warrior fund.
-Take my friends on a cattle drive/dude ranch.
...and probably have to keep working after all of that.
