Some gamblers are controlled by their wins in gambling. It is not that they are unaware or do not understand what gambling is all about, but after they might have won big in gambling, they are so sure that what they have won can still be achieved again.
Confidence in doing it again right, what a trap unknowingly to them, smart gambling should be the practice of every gambler to help oneself, the truth is, winning has a way of redirecting gamblers mind to do things that may lead them to being pissed, for instance a gambler who has been gambling for a long time and eventually luck plays his role on such gamblers selection that made him to win for just that once, instead of atleast dividingy the money into different parts use the higher amount for personal needs and some other stuff, he feel that he can make multiple times of the one the one he has won already with same money without considering that he is not the one that decides what happens at the end of his gambling event.
