What some gamblers most really should really take note of is that viewing gambling as a form of entertainment rather tha a means to earn money can help maintain a healthy perspective, a better understanding gambling can lead to a more enjoyable and responsible experience.
And that is what is common to them. They don't view gambling as an entertainment and goes on it as a ways of making money.
A thought that is common for most gamblers even you and me. I think we came from that point where we think that gambling is a way to earn money.
We've been there and done that but we've changed after all. And so, the common thought that each gambler that is hard to change is about that.
