if it was so easy, i don’t think there would be gambling addicts all over the world or gamblers who have ended up losing most of their money the truth is most of the time it is difficult because it takes effort and patience and most of all discipline which things that are difficult to enforce when you are having fun while gambling
Discipline is one of the things which will determine if the gambler can sustain himself or not. If the gambler is not disciplined enough to control himself, then every other factor is useless, as they will set a limit and break it. Even when they see that they are overspending, their lack of discipline will always keep on pushing them, and they just can't stop. Discipline and lack of control are the greatest problems of a gambler.
