For experience gamble its normal about how much loss and win, its not matter for them one day loss because the next will win so easily forgetting when loss position.
In my case it is different, I tend to forget whether I win or lose, because for me playing another day is another game session and I don't like to think or bring up past experiences so as not to repeat such mistakes, it's like a restart.
Actually there's no quick way to "forget" a loss in gambling; instead, the goal is learn to be patiently calculating to cope with loss because for as long as you keep pushing to recover what's lost, the more vulnerable you are to more losses.
While the intense frustration of a loss will eventually diminish with time if you are not too anxious, because you will likely always remember the rate of input and the loss, but you'll find ways to move forward with new approach.
I'm very sure that there are quick ways which a gambler can actually forget about his losses. I don't really know but based on my perspectives, a gambler can quickly forget his losses when he gamble with what he can afford to lose. Before you gamble with what you can afford to lose, you have known that you can not get that money when you gamble with it, so I think that's another easy way to forget your losses. Gambling with what you can afford to lose so that you can forget about it when you lose it.
