When do you stop? Do you have a daily limit or something?
I stop whenever my deposit already zero or when i'm too tired to play. If people used to use bankroll management and some kind of limit upon themselves, they will know how to stop and never cross the line.
Limiting yourself is the thing to do in order to know when we should stop. Limit your spending and overcome the amount of play. But all those boundaries will be useless if we break it or surpass it. Going beyond limits is what happens because of a lack of good self-control. Therefore we must first be able to control ourselves.
Decreasing amount using in gambling is the best thing we can do, because I know that if we set boundaries in playing games is not probably happen. Especially when they always bring our all money in gambling also if all our money was on the gambling sites. Because it's hard for us to fight our temptation especially in gambling.
