If you try to remember the sentiment when you lost money, maybe it will stop you from doing this again.
It won't. When you loose, you want to win that amount you have lost back. Same thing happens when you remind of the money you have lost: you regret and want it back. The trick of all the casinos, and gambling itself.
Yes right when someone looses then it is even harded to leave the gambling because person wants to recover back the amount that he lost in gambling.In winning yes person become greedy but its much easier to leave gambling at that point rather than when you have lost.
The best thing will only be try to forget about that loss but its really not easy to forget that,
Suggesting someone to quit gambling is easy but in real talk it's really hard to quit such thing specially when you are already got addicted to it. That's true that you always try to cope up your losses that why you keep playing and playing but in the end you even lose more. Self control is important on this kind of situation because if you have a strong control on yourself you would stop directly without worrying about your losses In the past.
