It's because we've been addicted, so even though always lose will continue to gamble. That's what i see from most gamblers i know.
once addicted always addicted. We cannot deny the fact that even they already realize that they are addicted they still want to continue to play. If an addicted person in nature will attached on that game, automatically he will surely never stop even always losing a game.
Don't believe on that, we can be addicted but that does not mean we will always be addicted, of course we can still correct our mistakes and enjoy gambling. Too much addiction will cause damage in our lives and instead of gambling to get the entertainment, we will never gonna achieve that as all in our mind is only money and we will always chase since we always lose for sure.
