Not only does it reflect the general personality, the results and attitude of gambling reflects more than what a person keeps inside them, some people are really good in their nervous and emotional systems when at least their vibration is only at low frequency all their life but once they approach gambling, what had always remained infinitely stable began to fluctuate and cause a confusing rhythm. Sometimes many people are also scared and do not realize their strange personality in gambling, it is almost two opposite and ugly versions that a person does not want to see.
Regardless, gambling is a true reflection of one's character and discipline in fighting and controlling one's emotions. It does really tells one's ability to withstand the pressure that comes with uncertainty. Fighting one's emotions during gambling is not as easy as mentioned by many. It goes beyond just controlling your emotions, it is also ingrained in one's ability to understand their inner self and identify their emotional weaknesses. From such knowledge, one's able to build some sort of immunity that kinda fight that urge. It exacerbates why one's gambling pattern and reactions exacerbate one's true personality.
I agree with you, and with those who are addicted are people who fail to protect themselves in terms of finances because gambling is very closely involved with finances. The number of people who fail in gambling always ends up with addiction and destruction in their lives, this proves that they cannot control themselves with the gambling they do excessively. In addition, emotions are also what I think are things that help them in the process of becoming addicted because uncontrolled emotions can make them do actions that are not considered first. People who are addicted are those who cannot control their emotions when gambling, especially when experiencing disappointing results such as defeats that occur so that when they are in that state they still insist on gambling to get the victory they want but that only makes it worse.
