Many times I heard bad stories about gambling experiences of people who are in need of money. Most of these stories are about people who are hard to satisfy honestly. We should never forget resources in world are limited and you can't win everything. I suggest people to gamble with low share of their wealth or wage and always consider quitting at one point even if you keep losing. Losing is part of gambling experience you should understand this clearly.
The problem is that is very easy to quit when you start gambling and you always lose,there is no incentive in order for you to continue,some people want to get their money back and they lose even more and become addicted but the majority of people when starting only with loses I have seen they have been able to easy quit.
The real problem is when you start gambling and you hit a couple of big wins in the beginning.After that even if a person loses he reminds himself of the big wins he got and that he hopes he will get even more big wins than those if he continues playing,this brings a lot of addiction to many people unfortunately and this also bring a lot of "worst" days in gambling.
