Give 5 million to my parents, sister, grandfather, grandma, and probably best friend's family.
With what's left I would buy a plane, boat, and car. Probably a couple of each. Keep my current home, but buy some land, 500 acres ish, with a decent size body of water on it.
Probably a waterfront home in Florida, and a nice sized cabin in Alaska. Hunt and fish whenever I like, as long as I like.
Travel the world, probably hunting and fishing while doing so.
Have my own workshop, in one of my homes, where I could build and tinker with things.
Buy every gun I ever wanted, most from WWII.
Complete numerous other things I would like to do in my life, scuba diving, sky diving, and get my pilot's license, to name a few. With said pilot's license I would tour the world in whatever aircraft I chose.
The rest would go in the bank.
That would be the life.
