but Still Craves Individual Interactions
Wins The Lottery
Most "Lottery" stories has the individual go on a sexual rampage and/or a buying rampage (buying buildings, cars, planes, even islands all willy-nilly) with little regard to realistic writing (to be fair it IS a kind of wish-fulfillment story but I would still prefer some realism). Also almost always the MC is either young or middle aged. I have read one story where the person wanted to cut themselves off from society and they bought a large ranch out in the middle of nowhere...but most stories seem to jump more into the party/travel/sex all the time mode. So I set the parameters to limit (but not necessarily exclude) the excesses I have found in other lottery stories. Maybe someone can use those to fashion a decent "realistic" lottery story that actually has a plot other than sex and excess.
My personal story idea would have the MC place most of his winnings in trusts and have the trust income fund his needs. I see him looking for a semi-secluded house, surrounded by nature but not too far away from a large town or city. He sets out to hire a live-in housekeeper/personal assistant. He wants a youngish (say 18-30ish) female to bring a shot of life to his daily boring existence. He wants someone that he can get along with and that he can trust... after all they would be living in his home and interacting with him daily. Personally I do not see them becoming sexual. Instead, the MC gets a chance to vicariously experience young adulthood again through the conversations/interactions with his new housekeeper/personal assistant. He can provide a sounding board for her troubles and advice based on life experience.
My vision of this story has her initially being a bit hardened and hurt from her past, struggling to try and stabilize her life long enough to build a solid foundation for her future. She slowly comes to trust the MC and with his help and advice she rebuilds herself, her confidence, etc. After 4-6 years or so, she eventually reaches a point where they both agree that for her to progress in life any further, she would need to leave his employ to spread her wings.
As I said, that is what I envisioned when I came up with the parameters. Anyone is free to take that and flesh it out to a full story or come up with their own background/plotlines.
