- Mental discipline: Such as analytical thinking, emotional control, decision made under pressure and even training programs since professional gamblers spend time to refine their skills by constant practices and experience just as athletes
I don’t know why we have to discuss professional gamblers in this topic.
Honing one's mental discipline is not only limited to professional gambler, infact it is highly encourage that all gambler should hone their mental discipline so that they can avoid unwanted gambling addiction to engulf their being.
I think gamblers hone their skills from direct gambling experience. Not many would think too seriously about studying it, except for those who really want to dedicate gambling as an income.
I think this is just half of it. Gamblers also learn from reading and analyzing other experiences. Actually, other gamblers' experiences give much more experience than the gambler's experience alone. Those who wanted to have a higher chance of winning will always do this kind of stuff even if it is just their leisure activity.
