have a client/friend that won a big one and I would do similar to what she did.
First off, I have no debt to pay off, other then mortgage so I would buy some property and build my dream home with a huge shop for all our hobbies. Work.......hell no, just for the fun of it most likely. Travel.........hell yes.
I would also put money away for my boys. And depending on how big the winnings were, I'd start some sort of foundation but not exactly sure who it would benefit. But would definately give some of it away.
