With all these examples, do you think it is important for gamblers to have a do list in case they win a huge amount, and what are the first steps they should take?
If a gambler has no financial discipline the list will not matter when they win a big amount of money because they will forget about it, dump it and start buying wants instead of the needs that they've written down on that list.
The first step every gambler should take when they just win a huge amount of money is to allow the money to cool down, that is not spending the money in a hurry or in a rush like under an emergency or like the money is not going to finish. Money spent in a hurry will be spent on many irrelevant things.
Knowing that there is a chance to win huge whenever you gamble, you should make a plan to develop financial discipline as a gambler.
