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?
For me, I stops when I am winning because when I already know that the I won the money my mind setting is "Yes I already have money time to go and tomorrow is another day". On the other hand if I am losing, sometimes my mind setting is to "OK try another one until you win". In that case I may continue losing.
