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?
