In order to control my losses and to lose only how much I can afford to lose, before I play I am already alotting a certain amount to it. If that amount is all gone, then stop. But if I am winning and that amount is increasing that is the time that I have to judge at what amount will I stop cause I am already lucky that I am winning so I do not want to lose the wins I've got.
That's right because if you keep playing even though you know you won you can still lose what you won. So we should keep in mind that we are not gambling just to lose, but I am not saying that we are hoping that we will make a big profit just by gambling. I mean we only gamble when we have a good mind because there is a tendency that when we gamble with anger or we send emotionally it is possible that our money is running out and we will eventually regret it.
