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..
An addict can change if he has found his saturation point in playing gambling where he feels frustrated never getting any wins and lots of debts which he has to pay off, usually gamblers like that will stop on their own and don't need advice, because with him not getting the way out of all the problems the only way is to stop and solve all the problems.
On the contrary it is debt repayment that makes an addict stick tight with the notion of trying his luck harder to repay. If you ask most addicts in gambling the reason for not stopping, they tell you that they are indebted and will stop soon when they repay. They promise to stop and give you timeframe but when that time comes they still tell you another date. Addiction is a serious habit that people may not be able to stop until they get help.
