2. Don't tell anyone
It will be damn near impossible not to scream and dance like you're showering in a cloud of hundred dollar bills, and announce your new net worth to your friends, family, and all of your followers on social media. But whatever you do, resist the urge and do not -- we repeat, do not -- do the latter for the sake of your privacy, security, and sanity. Think about it. Your finances were nobody's business but your own yesterday, so there's no reason why that should change, especially now that there's a greater chance there could be something in it for someone else. As Gandalf said to Frodo on that fateful night, "Keep it secret, keep it safe." Gandalf knows what's up.
However, your ability to keep a low profile could be severely hampered by pesky state lottery laws, seeing as some states require jackpot winners to come forward for a bit of publicity (think annoying reporters, camera flashes, and an oversized novelty check with your name on it.) Out of the 44 states that sell Powerball tickets, all but five states -- Delaware, Kansas, Maryland, North Dakota, and Ohio -- currently have laws requiring the lottery to release the names and place of residence of jackpot winners, according to the official Powerball FAQ. Other states may require press conferences and other publicity, but you should consult lottery officials in the state where you bought your ticket and your lawyer (we're about to get to that) first.
