I do not think it is a wise decision to gamble as today you may win a good amount of money which may lead you to a beautiful life. But who knows tomorrow you will not lose and it will not come as a disaster. So, better not to take it as a source of fund.
The casino industry thrives on this false confidence that gamblers gain before starting playing and also between games when the win something small even if an insignificant amount.
Gambling is a source of entertainment and not income. If you are thinking of the opposite you are doing it wrong and you have to correct it to avoid the long term addiction and monetary loss associated with it.
While there are some people who might brag about their wins, they often skip out on the grimy details or present their win in such a manner that it seems like magic. Dig deeper in the proper place and you will find the real thing.
