I can't easily stop when I am losing despite the fact that I already set up a limit to gamble in a certain day or a certain session.
It might because of the eagerness to recover what you have lost. Even we set a limit on how much to spend for the duration we're going play sometimes we dont follow it. Losing the money is depressing thats why its hard to stop and in the end you have this regrets why you gamble the money instead of spending it to buy food or other important things. But we have different way how to handle such situation and it depends on the mindset of a gambler. Its much easier to stop if you win rather than if you lose.
Agree, the odds of stopping when we win will probably be higher because at least in this situation, our eagerness can still be controlled when we start losing again, happy mood and profit are always a good point for us to handle situations and make the best decisions. While in the opposite context, the loss is only brought with a feeling full of wrath, the chance of stopping is too difficult when we are extremely bad, the only thought is to try to find what was lost but continue to lose what is possessed is the next fate, can not stop in the loss
