Have you ever been in a situation where you took a big loss. clearly because of your own mistake but instead of owning it, you ended up blaming the casino? Maybe made some excuses just to avoid feeling stupid?..
This is a common practice, when you win, you believe that it's all due to your own strategy, and when you lose, a person usually looks for reasons elsewhere, without acknowledging the fact that he made the decision himself and this wrong decision led to a loss.
That's how an irresponsible gambler responds to their losses. Instead of accepting the consequences of their decision, they will blame elsewhere, thinking that they are right. A kind of gambler who will surely never find themselves confident, because everything they do will always have an excuse.
This kind of person should not gamble in the first place. Because a gambler should know the risk and accept the consequences. If this is difficult for us to do, then gambling is not the right place for us.
