I'd probably sit on it for a few years while I'm in college, let it accumulate and get interest and all that. Then I'd spend some of it, use some to pay off my car and other assorted bills and perhaps spread the wealth a bit among family and friends. The majority of it would be used to max out retirement accounts and invested in various ways.

Being idle isn't really my thing though so I'd probably still work, just not at such a shitty job. I'd get a job I like in my career field (once I figure out what it is). Might do some traveling on vacations.

I don't think I'd ever need such an obscene amount of money though so I'd also figure out what to use it for after maximizing returns for a decade or two. Not necessarily charities so much as making a tangible, physical difference. Providing the funding for a complete overhaul of my state's transportation systems, for instance. Import a bullet train to use on the Downeaster line. Stuff like that.

At least, that's what I've worked out so far. I've actually thought about this very subject quite a bit. In case I ever get rich off my novels, hah.
