Well, what do we expect? They are addicts. But indeed that optimism seems not a right word to use there, since there is no point on why they continue doing it. They are like a cool guy when they say that being addicted is only just a minor thing for them. But for us, even a small loss is already a big deal. They look so confident when they say that, but deep inside there must also be a despair, regret and other negativities that they can feel.
We shouldn't blame or hate them but instead, we can do much better like trying to talk to them seriously about their problem. Once they get comfortable. That's the time they can confess and start trying to change their lives.
Our lives can either go in a good path or wrong path, all depending on the decisions we take. Comfortable gamblers doesn't have anything to worry about, rather they're satisfied with the current circumstances they've found themselves and wouldn't allow anything to disturb them. There's this adage in the space "it's better to be clueless about something other than knowing something that will ruined your peace of mind" it's very simple. Gambler have no intentions other than grabbing good profits in the system, I've watch my colleagues grown to become an addict because he was too desperate and didn't hold back other than pressing forward for results.
