When gambling for fun you don't keep records of any losses or losing streaks because it's doesn't matter to fun gamblers. We are just concerned about the joy we derived from the experience so there is no point of getting tired because you are losing because the losses are not taken into account. What we are concerned is gambling with money you know you can afford to lose and don't expect anything in return. The moment you start paying attention to losing streaks and money you have lost, then you ain't gambling for fun anymore.
The funny thing is that those that are gambling for fun are the ones that usually endup happy at the end because they don’t usually set their mind for any win rather they do it for fun so they usually don’t lose more during their gambling session because they usually know when to stop compare to those who are gambling for the money because they are usually desperate to win big , so they will try all means Just to win even going beyond their budget causing more losses for themselves.
I think it's because they are not too obsessed with pursuing victory, until they can accept themselves who experience defeat because defeat is one thing that cannot be eliminated in gambling so for players who cannot accept this, they will likely put their minds on wanting to recover the losses that occur. For those who aim to seek pleasure in terms of the sensation they get, they may be able to limit themselves, but for those who aim to make money, it seems they cannot control themselves well.
We must be able to gamble reasonably without an excessive budget allocated to gambling, because clearly that is a behavior that I think is outside the definition of gambling for fun.
