Step one is, of course, to pay off bills--nothing original there.
Next, I would allocate three million dollars for two houses: a Summer and a Winter house. The Summer house would be in a state like Oregon, Utah, Idaho, or Colorado--an outdoorsy place, but with good gun laws, and a Libertarian streak.
The Winter house would be in Hawaii. I'm thinking West Maui (maybe Napili.)
I would budget $100,000 to live off of a year, until age 90. And put some aside for kids' college, first house down payments, etc.
Then, depending on the amount I had left, I would travel and do the round of charities. The idea would be to set up myself and offspring in a favorable position, but leave nothing after death. I would also limit investments, as the government already steals too much, and I wouldn't want additional taxes.
