If I won the lottery, first off, I would quit my job (if i had one) because it's unnecessary to have a job when I have lots of money. Then, I would get a bigger house. I would also go out and get lots of cool things, like decorations for my house and a good computer.
But there are some things I would consider. If you aren't challenged in your life, what's the point of even living? So, with my money, I would start a business. Maybe one that specializes in computers, or art.
I would also want to be nice with my money. I could donate lots of the money to charities such as children's hospitals and help the poor. If I have lots of money, why not use it for the good?
So, if I ever did win the lottery, that is probably how I would use my money.
