Basically people know that gambling has risks, good and bad are always felt by every gambler, but people are still interested in betting, factors vary, depending on the individual.
My experience, gambling is a challenge for me, I can develop my skills when betting, I like challenges, actually gambling has a lot of good and bad impressions that I feel, where I experienced all that when I won and lost, it was a pleasure for me when I could beat the bookies.
I often say someone has been involved in gambling they are like being hypnotized, no matter how many losses they have experienced and wins, they continue to take the time to do it, that is gambling strange but fun.
