Indeed, the key is self-control, because with good self-control everything will be fine, including the gambling you do. If gambling is done with good self-control then there will be no emotions that will destroy the gambling being done, because if gambling is done with emotions then what will happen is chaos with rash actions. There have been many bad incidents with gambling done because of overflowing emotions. In my opinion, it's not just gambling, it's the same with other things, if we do it when we're emotional then what's likely to happen is chaos.
It's true that we have to be able to maintain self-control, but I believe controlling emotions is difficult, especially when the results of the gambling are not good, and if the gambler cannot accept that then emotions will control everything. then losses and other bad impacts can no longer be avoided. So it is important to control yourself and control your emotions properly when gambling.
Your points are good, but the part you mentioned that controlling emotion is difficult is the part I do not so much agree with. What you admit is difficult is what will be difficult for you, and what you agree is easy is what will be easy for you. Even if it is not easy, your dedicated effort can still prevail to your advantage. The reason why I emphasized on that is that the problem most gamblers are facing in this regard is due to their unwilling nature to fight as they ought to, they relax too much and give up so quickly, but these are not helpful to gamblers. The more we entertain our weakness, the more it bites and becomes an issue for us. The weakness of most gamblers is emotional and not the lack of luck or skills to gamble, and even if they planned best, emotion will still strike. This emotion of a thing is psychological and has to be handled psychologically and with strong determination and not the handling of levity.
This is possibly going to work if the gambler has a strong Will and Mind to fight and put things in the right state in their minds and also make sure that their plans are worked out as they should, which entails the control of our minds. Who says we can't control it? Once we are disciplined and determined at the said time, before we know it, we will see it done easily as if it was our daily doing that demands not much stress or effort on our part. But the moment we see it as difficult, the more it becomes difficult which is what most gamblers are suffering from. It depends on what you feed the mind.
The reason I say controlling emotions is difficult, because when we do gambling then it will change everything especially if we cannot resist the temptation of gambling which is strong, there is a possibility that we can experience bad things because we cannot resist the temptation of gambling. because if we cannot control our emotions or self, there will be arbitrary decisions that are not considered first, only a few people who in my opinion can control their emotions with the final results of the gambling that is done.
Well, with the number of people who have suffered huge losses and other problems I think it's because they are not disciplined in their gambling actions and that means they can't control themselves. This is true, I have heard it directly from a parent who gave direction to his students, he said that if the child thinks that what he is doing is difficult, the truth will be difficult, so the parent told him not to think it is difficult. Whether that's true or not I don't know. What is clear is that if gamblers gamble often or pursue losses I think they cannot control their emotions and themselves.
