Recognizing those changes can help you to adjust and to try coping up and battle against this issue inside you, gambling addiction came from irresponsible gambling practices, addiction begins when you keep pushing your way in winning with the games you play, at the beginning you just wants to enjoy and you are only being entertained but along the way, you will see that your appetite start to increase and your desire to keep on playing will lead you to engage a lot, without setting any limitation eventually you will see yourself going deeper and addiction already inside you and it's going to be tough solving this problem which already developed inside you.
I concur with all you said man. It's more like forcing what you don't know the end, most of the time it's disappointment that comes with eagerness to get something you can't control. When disappointment comes later, you start to act up in that game and instead of them to forget about the mistake and continue their journey, they are pained with the past trying to recover what has been lost.
I know of a guy one time like that, used his school fees to gamble but lost the money in the process. He approached his niggas for quick help to sort it but didn't inform them that he will be paying school. As a smart person, he was supposed to use that to pay the school since it was due already and then find for alternative to pay back, he went back and bet the same amount trying to recover the previous lost and still lost everything in the end. These are the problems we need to understand, gambling comes with responsibility and not by fooling around trying to win money.
For the recreational gambler an important characteristic to have is the ability to simply accept their losses, it is obvious that everyone wants to win even if deep down they know this is unlikely, however once you lose you should simply take the loss and move on, the people that keep being mortified about their losses are the ones that are the most likely to then make a life-changing decision which could mark them, and in the worst-case scenario this could set the stage for an ongoing addiction.
