Why we should forget about our loss(es)? I would prefer to say that it is better to accept the loss than to forget the loss.
Loss can be used as a reminder for our future or upcoming gambling session, so I will not try to forget it because once I can accept the loss then it is already fine for me.
If we should forget our loss while we are gambling frequently which means that we will have more losses the how many times we should try to forget those losses?
If you also look at it from another angle, if you don’t forget your losses it might cause a trauma in your mind and anytime you think about it you can begin to getting the feeling of fear. Not forgetting your losses can cause you to doubt your own prediction ability and you may start not trusting your own judgement.
In gambling I will choose to forget my loss so that I can have focus on the future games I will be playing without having to feel the trauma of the previous games I lost.
