Because they want to feel that big experience again, they don't realized how much money they are losing now.
We have enough with the experiences and it's time to spend money wisely. When you are not winning anymore, stop for the day.
You don't have to prove anything with what you have because that's just going to cost you a lot of mone when you are going that far.
Acceptance that it is not working on you will make you stop.
Accept the defeat and call the day and try to find a good way to refresh your mind, it's always the advantage of those experienced gamblers, they are equipt as they understand the risk of over-exceeding thier limits, though some times there's still lapses but they have better grasp of what's going on and they keep finding the right path to make sure they will not suffer for much worse outcome, but instead, they will be able to enjoy both the game time and some profits when luck is on their side.
