Yes, it is not an easy idea to do, meaning the point is I think there is only one option that can be done, which is to stop gambling completely and forget everything related to gambling, because as you said that in the end there will always be a feeling to get a big win unconsciously even though they initially planned that it was something that should not be approached.
There are so many things that can be a motivation such as gambling advertisements or news about big wins that have been obtained by other people as you said which of course I also agree that it can stimulate the brain and then you try it unconsciously, this is the reason why addiction or impulsive gambling can come and happen unconsciously, so as long as a gambler is still involved in gambling then all bad possibilities will still be a possibility that can happen at any time even though from the beginning they have a good plan to gamble reasonably.
Well, of course, completely stopping gambling is an extremely radical and tough option to avoid all the risks associated with gambling.
However, many players will probably only say indignant words to such a proposal, and maybe even many of the players will swear. After all, many players are so passionate about gambling, and it is such a huge part of their lives, that giving it up is extremely difficult for such people and for them it is simply a big loss of their life interests and incentives. Of course, this radical step has to be taken in the case when the player actually develops a gaming addiction at the stage of a serious mental disorder. In this case, of course, this must inevitably happen. But if a player still plays periodically and does not spend too much money, then it is probably better not to even advise him to give up gambling altogether.
Yes, although quitting completely is the best decision to get out of all bad possibilities, but saying it will always be much easier than practicing it, it takes adaptation and a process to get out of the habits they always want, but it doesn't mean it's impossible for them, especially those who are addicted to get out of the situation, but the process must be based on strong intentions and determination.
The key is to gradually realize your own mistakes regarding your perspective on gambling and the second is to change your approach to gambling in a better direction, such as eliminating thoughts of gambling excessively, and the last is the most important, namely by no longer making winning a top priority, and when all that is in a gambler's mindset, then I am sure that change will definitely happen even though it requires a fairly complicated process. Because there is nothing else but to justify all these perspectives and thoughts so that we are no longer trapped in pursuing victory and also to be able to have better self-acceptance regarding the risks in the sense of being able to let go of everything that has been lost, after that it's up to you whether you want to gamble again with good responsibility or stop completely.
