Some might treat gambling as a way out of their lives, their poverty that's why they go and maybe have the dream that they can one day win big and change their lives for the better. But the question is what if it didn't happen? So that's where the illusion come into picture as they become delusional. But whatever the case maybe, as gamblers it's better to just play for fun and not put any pressure on us to win. It could be that win might come in any form or when we least expected. Maybe that is the real secret, don't force it, as we don't know that lady luck may came in one day without us noticing it until it happens in front of us.
Sometimes you cannot blame completely on those who want to use gambling as a escape route from poverty, for some one who hails from a developing nation, little to almost no means of survival and very scares job opportunities and yet they hear and sometimes see how a few persons gets to win big and have their lives changed thereafter, the next thing they will do will be to opt for a trial to see if they will be the next lucky person.
This isn't me supporting such mentality but stating some actual reality. Playing gambling for fun sounds like the healthiest way of gambling until you get addicted to the fun and start loosing yourself to it then you think gambling for fun was a better thing you would have done but see you are now loosing yourself to it, be it for fun or money, always have a limit of gambling beyond which you do not gamble, maybe that will help even for those that have dreams or those that just want to gamble.
