Of course it is very easy if gamblers can stop their gambling habit if they continue to accept defeats in gambling. But for people who are addicted to gambling, it will be difficult to stop... because it has become their habit. every week or even monthly to improve his family's economy.. it's impossible for him to stop..
People need to understand that gambling is not something that can improve the financial status of their family or themselves but it is just a luck-based thing where you might win sometimes when you are lucky but you will lose more in the long run, and winning in gambling cannot be constant, you may lose $20 today but you are most likely going to lose $40 the next day, or the day after that, so having high expectations from gambling is useless as that will only hurt you at the end of the day.
So it's better if someone doesn't ruin their lives and lose everything they have only in trying to earn a living for themselves and their family because once you get addicted to gambling, it is too difficult to get out of it and you won't stop until you have sold and used everything you own in gambling.
Also, the most important thing to realize before gambling. that, gambling involves risks contained therein. that means, every penny we bet has the potential to lose. that is why, one must realize that when he first tries gambling, he must be prepared that the money at stake is at risk of losing. if we try to calculate the amount of loss from gambling, even that in the long term. better, never do it. because in theory, what you say is true.
First, people have to realize that it's not something that can improve financial status, be it income or something else and so on. second, we might lose $20 today, maybe $40 tomorrow, even the day after tomorrow will experience even more. concept like this, is not ideal when applied to gambling as I said. because, once we try to make a bet, we are consciously prepared to lose the money at stake. ideally make it a fun hobby, because every hobby will require sacrifice be it money, or so forth. that way, we don't need to calculate the money we lose in the long run. however, should be underlined. that every gambling session, does not mean we let our money just disappear. that's why, extensive knowledge and insight is needed. also, responsibility. At least, we can minimize losses. also, make gambling just part of the fun and enjoy.
