This means that in any situation regardless of winning or losing a gambler must still be able to stop, the benefit is that in addition to being able to prevent a gambler from significant regret, this idea can also make a gambler enjoy the results of the victory he managed to get.
I understand that it is an idea that will only be easier to say than to do, because most of the cases that occur are often most of them are too confident as you said above so that they do not hesitate to continue their gambling session by applying greed.
But actually it is an idea that will not be too difficult to do if only a gambler understands the opportunities and is aware of the risks.
As I often do where when I manage to win any amount such as 2x the capital, then usually I will first cash out half or 80% of the total winnings and then continue the game with the rest. It's about how smart you are in managing everything.
Yeah that's a wise decision, instead of completely quit when you've achieve your target, it's better to leave some funds to gamble more when you withdraw your profit. If we always discuss greedy during win and lose, but someone can be greedy when they want to withdraw their money, they're greedy to take all the profit.
Sometime isn't always about money, but we also need to spend time to kill our free times.
