If someone can control himself in gambling, it won't be difficult to do. But the problem is when someone has played gambling too much, he can use more money because we know that playing gambling has many temptations and not many can resist being tempted.
But having good self-control isn't something easy, it can be mastered after you got a lot of experience. In this case, the may not have enough experience in gambling, so he gets difficulty controlling his emotion. Anyway, playing too much indicates that someone has no good self-control, he won't do something excessively if he can control himself well.
Using the money we can afford is a sentence that we really have to remember and we shouldn't forget because that's what can make us really limit our gambling. And even though we can't control ourselves completely yet, we still have to try to control ourselves because we don't want to experience defeat and spend all the money we have.
Limiting money is one of the ways to control our gambling habits. It also prevents us to waste our primary money. However, to have good money management, someone should be mature enough. That's why it is forbidden for kids to gamble. Only when you are already a mature person that you know the limit and have the ability to control yourself. Sadly, in this case, the boy is already 22 years old which means he is mature enough. This means even if your age is mature enough, no guarantee of safe gambling if your psychology is not mature enough
