Mega Millions Mania

Assuming after taxes I get to keep more like $300 million...I'd invest a good amount of it to ensure that I and my fiance can live comfortably and travel and so forth without worrying about money.I'd buy a reasonable condo or house. No mansions. Nice, with enough room for us and some guests, but not our own private hotel.I might open up a business selling custom-made gamer PCs or one of my other hobbies just for something fun to do.For the rest, I'd like to think I'd do some heavy charity work. Not-rich-me imagines rich-me as a wealthy philanthropist using my significantly greater means to right some of the wrongs that disturb me so greatly today.In reality I fear I might disappoint myself - when I get a financial windfall, I tend to be rather irresponsible with it. The urge to spend for immediate gratification for myself in the moment is often sufficient to overcome my well-reasoned desire to use the same amount for a better purpose in the future. My usual defense against this tendency is to simply not go shopping and not even pay attention to the sorts of things I like to buy. This may not work with hundreds of millions of dollars burning a hole in my pockets.But I wonder what $20 million donated to HIV/AIDS research could do for the world. Or a major political contribution (through a SuperPAC, natch') to a third-party political candidate who better represents me than the two mainstream parties. I wonder how much it would cost to set up a true non-profit health insurance company, and how effectively such an organization could focus on health and quality of life instead of budgets and denying care. A nice donation to the (tentatively named) Center for Modern Rationality (a real startup nonprofit intending to focus on new teaching methods to improve critical thinking and rationality) would be on the list as well.I'd like to think I'd do at least something good with that much cash.
