I'd buy a very nice house large enough for two or three people, put up some solar panels, buy an electric car from Tesla, pay off my depts and those of my close family members, and would invest the rest. It would be nice to make enough from dividends to live from week to week. Oh, and that would also give me the freedom to continue on to a PhD program, which might hopefully lead to my finding a job I really enjoy. There's so much I'd want to do if I had the time and money, but those are some of the big things.
