Sometimes a person here and there is in the news having won a jackpot and fabulous amounts of cash are awarded to them. Some people take a long sober look and invest the money in passive or active income activities like rental houses in the case of the former. Others stop working and enjoy the money little by little till they exhaust the cash. Still others die due to recklessness and drunkenness. What would be your personality if you get such a windfall?
I've had a few over the years. My advice? Well, it is super boring, but very effective: save some and invest the rest in a vehicle that will grow your wealth. Rinse and repeat. Another option, if you have any, is to wipe out debt.
buy an old house well away from other people and any habitation. prep it to the hilt, private water and private drainage.
