What I would do if I won the lottery
The power ball, last I checked was 430 million. It will go higher. Have you bought a ticket(s)? Your workplace doing a pool to buy a pile of tickets? Like most people, I have some personal things to take care of. The real story, "What matters to you"? I am not materialistic. I'd pay off my debt, invest in some real estate, donate to my favorite charity, then establish a foundation to manage and grow the funds.
You have to get in it to win it! Statistically, you have a greater chance of being killed by a vending machine.
