Give my kids a million each. No more... don't want to spoil them!
Invest most of the rest in real estate, buy as many income producing properties as I can. Put a part of it in the bank so I could live off the interest alone. And invest the rest in guaranteed return financial products. (small return but guaranteed, vs. stocks, potentially larger return but no guarantees, plus possible loss of principal).
My plan would be to leverage the winnings into income-producing properties that could be handed down to my kids and become their "career" if they wanted it. Or they can sell off the properties and do whatever they want with the money.
This sounds like the Dave Ramsey Plan.
This is a good place to start a financial plan. I'm trying to get on board.
