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?
Obviously it is easier to stop when you are losing than when you are winning. As long as you are being fortunate with your game, you should just keep on going but still be mindful of the money that you have already won so that even if you'll lose later on, you will have some extra money hidden from them. In the end, you will still be winning amidst losing. If you are already losing for too many consecutive times, take a break and strategize then come back again to play and try your fortune once again and see if it is your time already.
