What you say is absolutely true because I have seen many gamblers selling their flat luxe cars and their wife's gold jewelry and getting rich all around me. I invest in gambling sites myself but I never do it to the point where I have to gamble all by myself. Always tell my friends to control themselves from gambling sites. Those who have chosen it as a profession should always never invest in gambling side outside of it.
I don't think gambling is bad, the only thing I know is bad about gambling is addiction, when you are addicted to gambling all what you have worked for you can lose all within few hours, whenever you are gambling always have a limit, always know when to stop and you shouldn't gamble with all the money you are having, some people claim they are professional gambler and some always say they are always lucky whenever they are gambling but just believe you won't always be luck and even professional do fail sometimes. We should always have limit, we shouldn't be going to the length of selling properties just because we want to gamble.
