A gambler's life is divided into two periods, when he is not addicted and therefore can but does not want to quit gambling, and when he is addicted to gambling and cannot quit on his own. The problem is that a gambling addict believes that he is not addicted and can quit gambling at any time.
Probably then there is a third stage, almost like with inveterate smokers and alcoholics, when a person addicted to gambling realizes that he has an addiction, but cannot get rid of it. In this case, it is good if he is ready to work on changing for the better, then with the help of, say, relatives or specialists he will be able to get rid of his bad habit.
