I've seen case scenario where people make good profits and never visit gambling a again and already invested in other businesses and today are still doing well.
Most times people want the easy way to make money and gambling seems to be that way that's why most persons wouldn't mind to lavish a huge profit with hopes or getting a bigger one and that's one thing that also drags people to addiction.
I personally can quit gambling after a huge winning bjt it all depends on the amount won because money worn are sweeter than money earned and that's one thing that will keep dragging people to gamble.
It is easy to quit gambling after winning huge but there is no guarantee that you will be able to quit gambling addiction. It is called addiction and that is why many gamblers fail to leave casinos even after winning big. We may educate gamblers who suffer from gambling addiction, anyways mental health is not going to be ok with a gambling mindset, IMO.
Well, there are some gamblers who truly had the courage to leave gambling after achieving what they wanted but its percentage is undeniably low because not everybody had the same courage and strength to leave the world of gambling and besides, it's certainly not that easy to do because before we can come up to that situation, we have already accustomed ourselves to gamble and that makes it difficult to end.
