i never estimate my losses because i know it will only turn me down,what i am concern mostly is the amount i won and that brings me positive feelings.
i know a man that writing in all his gambling activities,from losses and winnings and he tells me that it made him sick sometimes checking how much he losses while the amount of winning is very little compared to others.
Yes true once you think your loses you feel weak and turn down so its been better to us not to estimate our loses. Just gamble and have some fun so that every time you lose you don't be sad and you think it's okay because you have fun and feel happy to gamble. Don't waste time to think and estimated your loses.
Think of it as payment for your entertainment instead of thinking that you lose certain amount of money. The very reason why many people / gamblers always say use money that you are willing to spare and forget so you don't need to think about it after your game. Enjoying while your stay can be a stress reliever but calculating will add a lots of stress to yourself.
