First thing: go on here and say to watch the NEWS!
Short term: schedule a Vacation Day (did this once for a small claim) to Lottery HQ in Lawrenceville, and validate at the Store where purchased. Pick a nice shirt like "Feeling Lucky?" to wear to the HQ. Pick some cool MuSiC like "I Wanna Be Rich (Calloway)" and bring camera to take photos at Store. Day of trip to HQ if time stop at Molly Pitcher because they have Roy Rogers. Try to go early because sun at bad angle later in day at HQ and going there.
People who usually avoid or ignore me, now suddenly talk to me will be asked where they were when I was poor. I will tell some of my family they don't need my help and to continue spackling their ceiling. I would then offer for free whatever program I used whoever can use it.
Medium term: buy some oil and gold becuse those are likely to go up again! Purchase hybrid vehicle at some point, maybe Prius plug-in. Plan move to Bergen County (decent house with wide garage but not huge). Plan trips to Pittsburgh and few other places on the "bucket list" but nothing overseas. Road trip during long Holiday. Develop stock plan for portion of winnings to be used. Get all Dental taken care of. I have mostly everything I want so there are no big shopping sprees planned. I'd still do my own brakes.
Long term: try to figure out the meaning of life since you can't take it with you.
The short term is the most fun because of the excitement of having won; long term I might get feeling down sometimes, especially since playing the Pick-3 won't be as much fun.
(Watch with the "never gonna win"... I had 5 of 5 once. Using a program.)
