[Error: unknown template qotd]Cynical answer: What newfound riches? I'd be taxed into oblivion by Obama and his socialist policies in order to finance my neighbor's inability to spend money non-stupidly. A normal person would make sure they had electricity and water. My neighbors buy dogs.
Rather practical answer: Pay off my student loans, buy my own apartment and car, and then stash some winnings aside to help fund all the attempts to get my books published. I wouldn't quit my job, 'cause not working drives me crazy. I'd probably also start some sort of charitible fund or donate a bunch to my alma mater...
Dreamy, pie-in-the-sky, all-for-fun answer: Visit every place I've ever wanted to visit: London, Berlin, Athens, Sydney, Disney World, etc. Buy gorgeous, uninhabited island somewhere warm and start my own country so I can be a princess.
