An exit plan lacking is what makes these problems come in the first place. If the person is focused to win and then use the money in places that they are already decided with, then things are clear and they would not experiment with trying to make more money or try to win another jackpot.
Planning financially, it is lacking along with planning for the possible future.
And it's really those who have won but not be financially literate as they haven't seen this kind of money before. So they become their own accountant but then uses all their money without thinking of the future.
That's why winning lottery is also a big responsible to those people as we have seen that in just matter of years, if they don't know how to handle their money, in at instant, they are going to lose everything.
Good for those who learn to take care and invest and build generational wealth.
