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,
