I like to know your opinion about the question because I believe every gambler has a different way of managing himself.
My answer to the question is I can easily stop when I am winning because I am afraid I might end up with nothing since I know to myself that I am not yet consistent enough to win in gambling, however, based on my experience, 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.
Do we have the same attitude or not?
I find it much easier to stop then when I am winning a game, I am the kind of gambler that wants to enjoy my winnings by having a drinks or celebration, although I also have control when I am losing but stopping when winning is the hardest thing for me.
The major and hard thing for you is easy which is to stop in losses beacuse human are such that always want money back or play to recover those lost money and only if you have self control can stop it . While when you are winning at the max you lose that winning amount if you continue gambling and then you may stop once you lose all your winning so effectively you lost nothing from your capital side .
