Half of my winnings (or half of my monthly/yearly installments if that's how I chose to receive payment) would go straight into a high-yield savings account or CD that I could not access for at least 10 years.

Then I would use whatever was left to help pay off my debt, my parents' house, my parent-in-law's house and cars. Then I would probably buy a new car, and depending on how much I won.... buy stuff for my close friends and family (like if they needed a car, or down payment for a house, whatever).

Move out to the country with at least 15 acres of land, build my dream of owning a kennel and when I become a vet operate from my own home as well as run a boarding facility for cats, dogs, horses, etc.

And donate a lot as well to random organizations and charities.
