I would pay off all of our debts including our house, give some money to my brother and his family so that they could purchase a home. I would set up an education fund for my son. Then I would renovate the house and start looking for a new one in England. Finally, I would open up some kind of retail business.
My church (well the conference/governing body) has a history of not accepting large donations that come from lottery or gambling winnings. So I would donate to some of the church programs and missions in lieu of a cash donation.
So nice to have a little daydream this morning. :)
