That's one of the bad side of monitoring your records, as you will keep remembering your losses and the amount that you will try to recover,
most of the time, a gambler who knew the amount that he had already lost, got that mindset to try and recover.
I know that I already spent a decent amount in my gambling activity from then until now and the idea of keeping records of my losses can't help me to move on. So what's the point? Some gamblers might think that they need to keep playing to recover those losses (if they record it) and it doesn't feel good to have such feeling of guilt or eager to chase it back. Therefore I better record my remarkable winnings rather than the losses because good memories are worth to remember.
