I've found money to be a magnifying glass.
If you're an asshole and you get a bunch of money, you'll be a bigger asshole. If you're generous and kind, you'll be kinder and more generous.
Habits determine everything. For example, BlokBlok works out regularly, eats well, and has a good physique (yes, jeffery you do too, don't get all butt-hurt). If I were to add 50 pounds of fat onto BlokBlok's body, what would happen after 6 months? It'd all fall off because his HABITS (regular exercise, a healthy diet *Chipotle*, etc.) lead to him having a good physique.
So with these Lotto winners - why do they end up broke and in despair? It's not because of the money.
They end up broke and shitty because money was a magnifying glass... What type of person regularly plays Lotto? Someone who thinks that wealth is acquired through luck, is probably not financially savvy, and is probably not educating themselves on how to create wealth (since they're playing the Lotto in the first place).
The fact is, Lotto winners are typically broke - financially, mentally, or both. If you give a mentally broke individual a sudden influx of money, they are going to find a way to get broke again. Money doesn't fix a broke mind. Their habits haven't changed, so they will continue them regardless of how much money they have.
Like the example above with BlokBlok - if you were to take 100 pounds off of someone who is perpetually overweight, in 6 months, where will they be? They will be grossly overweight again. Why? Because they have bad habits (little to no exercise, bad diet, etc.)
If someone has good financial habits (saving, donating, investing, tithing, etc.) they are going to do good things with money - because they already have a good understanding of how money works properly.
If someone has shitty financial habits (overspending, overdrafting, payday loans, borrowing, excessive debt to buy "stuff") I'm willing to bet they end up broke no matter how much money you give them.
