Quitting gambling can be a difficult decision for active gamblers especially when they have just made a lot of money. It is very difficult to control desire when the urge to play has grown, this is the same as active smokers or alcoholics, they will feel uneasy before their desire is channeled.
Few people are able to control themselves to quit a habit that has become a routine in their life. Some people gamble not only because of the prospect of winning, there are many motivations for the habits they often do, one of which is because they are buying entertainment for themselves after doing boring activities elsewhere.
