If speaking generally of gamblers it is difficult to be able to control oneself and stop gambling because the impact of gambling is addiction which when a person does not gamble then he will feel anxious and even feel his life is meaningless.
Even so, gamblers are slowly starting to have a lot of awareness by using gambling as a means of having fun and looking for busyness while on vacation from work.
The beginning of a gambler who is able to be aware of the negative dangers of gambling when he has experienced a truly bitter experience and anyone must have been approached by this bitter experience.
The self-control factor is a very important action in gambling, because I think self-control is the only step that can be used to help us or minimize losses due to addiction and in my opinion every gambler should be able to prioritize self-control, especially when they experience defeat. But in the end, it cannot be denied that most gamblers will forget all the things they had prepared beforehand, gambling moves under the human consciousness. My point is that most people when they gamble will forget everything outside of the context of their gambling, including some of the self-control measures they have prepared beforehand. This is caused because it is too cool in the game.
In gambling, someone will move subconsciously and their passions or emotions will completely control them, so that in the end they will not realize that they have lost a lot of money or valuables that they have. Lately, there have been lots of cases reporting the negative effects of gambling, some of them even experiencing stress. It's true, as you said, one of the things that can awaken them is when someone has tasted the bitterest thing in gambling, and maybe after that they will have the opportunity to quit their addiction, but the feeling of regret will still be there within them.
