I'm curious at what my fellow era members would do if they won.
Get a team together of advisors, financial planners and attorneys. Find out if I have to publically disclose who I am, If I do, then I would create a blind trust created with someone from the team to act as the spokesman.
I'd take the lump sum, as pretty much everyone agrees that it is better to take the lump sum. I'd create a foundation and invest a large portion with proceeds going back to the foundation, which I would then start donating money/goods/resources to worthy causes that I believe in (Conservation, Renewable energy, Education, Clean Water etc)
I'd buy a new home, because I really want a bonus room for the kids, so they don't trash the rest of the house lol. I'd quit my job in the insurance industry and commit myself to discovering worthy non-profits to support.
That is about it.
