I have a comfortable life right now and don't see a need to do anything wildly extravagant. I'd keep working, which, in my case, is school. And my family and close friends would certainly be told, but I'd try to reduce any media attention because lottery winners get inundated with requests from absolute strangers and, for that matter, distant relatives.

I'd get a good financial advisor and attorney. I'd save and invest. Set up solid trust funds for my cousin's kids and better endow the one our son has now. Modify my will. I'd give as much as possible to charities and causes I care about. Then I'd probably do a whole lot more traveling during semester breaks from school. Depending on the amount of the jackpot I won, I might buy two or three art pieces I'd like to have--and I'd probably further indulge my taste for antiques, too. That'd be about it.
