Many people really go too far when it comes to betting or gambling because they are greedy, and they let their emotions slide, whether they are continuously losing or winning. So my advice when you are going a bit far in gambling is to learn to be contented with your losses and winnings and learn to control your emotions, which means you shouldn't make sudden actions just because you feel lucky or you are going to win a round. Sometimes it's okay to let all your losses disappear in gambling because it helps you learn that not everybody will go home with their winnings, and this will help you to be satisfied or be contented with your losses or winnings.
Yeah right, but for sure it's easy to say than to make in action, just like what you said due to greediness and the emotions that controls your mindset during your gambling sessions, it's a hard battle with you that needed to control, if you manage to beat your own lust then you are good to go, as you can tell yourself that you are quitting for a while to rest and to refresh yourself either you are winning or losing with your gambling participations.
