You are right. When one gambler will go for gambling in most cases he will face issues with the emotions. But if the gambler cannot tackle it then it is natural that he will face loss Or his losses will increase. If you gamble with emotions, you will make wrong decisions to win again and again, and in the end it will be seen that the amount of loss is much higher. So I think always should avoid emotion in these cases and go into a strategy.
While gambling we should follow some rules like gambling if we win a good amount of money then we should refrain from gambling and if we lose a large amount of money then we should refrain from gambling because then it will be difficult to control our emotions to lose. There is a possibility of losing more money to recover the money, so then you should avoid gambling. You should avoid gambling with hasty decisions. If gambling can be played in this way, then it seems that there will be very little risk of losing money.
