True, the problem is that it is not that easy to do some of the actions that are recommended and also the best to do for good, one of the reasons is because as you said that there are so many temptations in gambling that it can make a gambler even forget some of the limits that they have made before and also as we know that everyone has a "forgetful" nature in him, so it is very possible that they forget some of the limits or controls that they have made just because they see and are tempted by the many temptations that are in every session they do.
I think one of the keys is "decisiveness", you need to really apply this to your boundary planning because this is the only way you will at least be able to realize that everything you see is nothing more than a temptation that ultimately makes the situation worse, like when you are in a winning situation where most gamblers apply greed that ends up in a much worse situation.
Yes, the nature of forgetfulness is within a person, it is natural and as time goes by, because of this nature of forgetfulness, he will often act carelessly and unnaturally so that he actually does things that should be avoided. In relation to gambling, a person who is forgetful tends to get used to playing as he pleases and it is easy for him to forget the limits and good control in gambling.
Yes, I agree with you to prevent and minimize this by having firmness and discipline to maintain our control when gambling so that things that harm us do not have too big an impact.
A person will only experience "forgetting" when they are in a situation of weak awareness which makes them more likely to do things that should actually be avoided in gambling, and this means as I said above that the solution is that whoever it is must put firmness in their awareness, especially when they are carrying out a gambling session because with this I think it is less likely for you to always make mistakes due to the many temptations that exist in gambling. So the point and solution, as I mentioned above, is that assertiveness has a very important role in implementing awareness and boundaries within yourself so that you are not easily tempted by something that looks very tempting, and clearly the benefits will be to prevent you from all bad possibilities. which is not desired.
