Behavioral change is common depending on the mood or what happened to your day and not just related to gambling. There times that you'll win or lose in gambling, there are times that you are happy, irritable or frustrated, but it's important to be aware and of these behavioral changes and potential impact on ourselves or those around us.
This is true because it will make us a bad person. We get sad or frustrated, but that's it; we have to move on and continue gambling if we still can. But if we are still in the situation many times that we are having a hard time to move on, then accept early that gambling is not for us; otherwise, it will only destroy our lives and people around us.
We have to view gambling as entertainment, not a way to take us out of poverty, as although it's possible, it's hard to achieve such a goal through gambling, and most of the time, it will only lead to more problems. It happened to some gamblers, so it's not impossible to happen to us. The key here is to determine its risk and prevent things that might result in regret in the end.
