In gambling , it is not terrible to lose , it is terrible to win, because after that you want to win more and more .
How is that terrible? that is the reason you are gambling. People are gambling because they want to enjoy or have fun spending their money and trying their luck to earn a huge amount of it easily but that doesn't happen since we all know how cruel gambling can be. There are a lot of lives ruined because of it that is the reason we should be a responsible gambler.
Gambling will only be good for the individuals who are having a lot of money with their wallet but it might be a nightmare for the others who are in limited resources.
Cause gambling is not all about of winning but we are in here(supposedly) just to please ourself away from stressful life with our job.
So we can't consider this a good source of our income.
