True. Being a responsible gambler takes time to do if we are stuck in a way that we are having no discipline to every gambling activities we try to be part with and our habits and behavior tells us who we are when gambling our greatest enemy is ourselves that is why we tolerate ourself and set aside the time to change.
The problem is that greed makes it difficult to maintain discipline. A gambler who is greedy cannot make a sound gambling decision. At the end of the day, the gambler is the problem, not the bookies, and some gamblers are adept at assigning blame.
The problem with greed is that everyone has some level of it, making it difficult to suppress in some situations. However, a gambler who is unable to maintain discipline has no justification because other gamblers, despite the presence of greed, control their greedy urge and stay healthy in gambling.
