Yes, I think that's the point, what I mean is that everything a gambler will do will definitely depend on how they see the activity from the start, simply put, if from the start they misunderstand in the sense of seeing gambling as a place to earn income, then all their actions will tend to always lead to excessive aspects, and this is also one of the reasons why it is always difficult to give them advice because after all they will only listen to themselves, in fact it will be very difficult to convince them that excessive gambling will actually lead them to many dangers, they will never come to that thought because their thoughts are controlled by an obsession with winning.
But on the other hand, what you said is also true in the sense that even though from the start someone comes with the right understanding, it does not mean they will continue to be like that, it is very possible for them to eventually experience changes, especially in terms of their way of thinking and perspective considering that gambling is full of various things that look tempting, and in my opinion to minimize it is you must always be able to maintain awareness in yourself every time you play.
Self-awareness and good control will be your way of defense in terms of changing up your mood when you are inside gambling, both excitement and frustration can affect you when deciding your way, if you are well-aware and you know how to control your own emotion it won't let you to push your way forward but instead, it will keep you away from getting aggressive with awareness that you might be exceeding from what supposedly your budget or target.
Yes, that's how a gambler should be, so the conclusion is that the first and most important thing is the right and proper knowledge and understanding of what and how gambling really is, secondly it will make you aware of what should be done in every situation such as stopping when you have won or stopping when you experience the first defeat, and thirdly it also means that it will be easier for you to control yourself, or what is meant by awareness will encourage you to be easier in controlling yourself and staying within your limits. On the other hand it also means that gamblers who often play by being controlled by lust and obsession with winning are those who do not have the right understanding and knowledge about the concept of winning and losing in gambling.
