What contributes to a casual gambler becoming an addicted gambler is, the joy of winning when a gambler predicts and win then the person believes that winning is a normal thing, believing that I'm going to win will Make the person always want to play away, which is impossible that one will stake 5 good times without losing. If you play gamble five times in a week and win throughout that week the possibility of winning next week must be 50/50, so always believing that winning will always take place will lead to the addiction.
So fa so good, gambling contributes to richness so the joy of winning and getting rich will always make a gambler to always want to stake always and what so ever that makes a gambler stay without gambling everyday, there's a symbol or synthom of addiction. Normally gambling is not by how many things you gamble but, how many lucky things did you predict and stake. Must at times so gamblers will not sleep at night just because there intension is to predict all true out the night and sometimes stake at night but sometimes predict in the night and stake in the morning.
For some gamblers they will be at work and will leave the work at working hours and will move over to a gambling site and begin to play gambling and while some are students they will let go off lectures for gambling and at the end of the semester will be having a poor results.
All this becomes a behavioural this other then at the end of the day leads to addiction, to my own definition addiction is a state of mind of an individual that disabled an individual to know what to do at the right time, addiction to contribute to the unconscious control of an individual to leave the rational thing for the irrational at the necessary time.
