Setting a budget is very important to be able to control gambling activities well, because without these limits we can lose more money in gambling. But of course this is not something that is easy enough to do, especially in the long run. At certain times we can spend more money in gambling, such as on holidays or at the beginning of the month when we receive our salary. Well, that's when we really have to apply the limits that we have made, because believe me once we break these limits, the limits can be lost, and in the end we gamble without limits. Therefore, we must be able to respect all the rules and limits that we have made, and never violate them for any reason.
Setting limits and adhering to them are two different things. This is similar to creating a reading schedule; adhering to it is another matter. Gambling can be alluring, particularly for those who are desperate to win. The gambler finds it hard to stay within his budget because he starts to view every gambling session as a chance to win and recoup losses. When a gambler has money, it takes a lot of self-control to refrain from gambling.
You are right, setting limits take desire for responsible gambling or desire to gamble responsibly, that is to say that a gambler who desires to practice responsible gambling in a manner that it doesn't put a strain on them and their finances goes to setting up limits.
But on the other hand, adhering to the set limits will require what we all know as self discipline, this is what determines whether or not the gambler is or will be successful in adhering to the limits he or she has set for him or her self.
It is often said that giving a monkey a cup of water is not always a problem, but the main problem is how to get the cup back after the money must have finished drinking the water, in the same vain, setting limits is not always hard, I mean, any body can set as many limits as they want and desire, but just as you have said, it doesn't just end at setting limit, adhering is a another thing completely, and only those who have trained themselves well and mastered the art of self discipline can win in this regard.
