Weel let's see - after Uncle Sam takes his 30% of your winnings, I would find some folks who could wisely set up funds/trusts/foundations and then hopefully I live in a state where you can claim the winnings anonymously because not all states allow you to be anonymous.
Then I would pay off our few debts, build a new simple but well built home (and move out of this double-wide that needs so much work and only has 7 foot ceilings), with a wing for my daughter and her cats, a nice area for our son and a nice guest room for my sisters; we need two new/used vehicles, build a new small barn; buy new carpet for our church, new upholstered pews, new windows, and have professionals paint the church in and out; take a family vacation (we have not been on one in over 25 years); buy my sisters duplex, remodel it and give her the joint debt-free; choose 12 people a year to give $$$ to anonymously; set up college scholarships for older females wanting to return to school to better themselves; hire a detective agency to find out what happened to my brother; plant more trees; have a professional cut my and my families hair every month instead of me cutting it; continue to shop for bargains, spend wisely, live simply, laugh often, have more fun, give more often, be thankful for what I do have and not what I want. Oh, I guess you would have to buy a ticket to do some of that! Silly me! I will continue to live teh wonderful life I have. The headaches of winning are not worth the losses that occur.
