There are really people would always mind on their past games which could contribute on their emotions and would rage up their temper and with that they would make wrong decision when they do gambling thats why its really important to control our temper and we should not flashback the past.
That will be a never ending emotions, when we gamble we should always think fresh and forget our previous losses, that more we chase are looses the more we lose.
I think it can be happen if they are losing a lot in gambling honestly for me it can be trigger and cant control my emotion in gambling if i lose instead of recovering it i thinking to bet more so that i can recover my loses once i win but the result are still lose.. and i know that you will lose in gambling so i am not thinking about previous loses.
