It seems one thing is common between you and me, we lose our bankroll at the end of the day. For me gambling is fun and a way to escape the boring time I have. I don't mind losing but when I lose too much then I give a break.
If we don't lose then all these gambling business will be bankrupt LOL
Having the right kind of emotion takes you through the awareness that gambling is luck base and so you don't need to depend on it all day for finance which is why most gamblers find themselves struggling with it, they want to recover their losses by all means but that is not going to happen because in gambling you lose more than you gain and this is the right mentality.
Also as an old time gambler, you should know when to walk away if your loses are becoming excess. It is the newbies that are suppose to generate money for the casinos at least because of their lack of experience until they are also technically equipped for it.
The chances of luck or defeat will not care about whether you are an old or new gambler, both things will always come to you especially defeat, and for the difference between these two gamblers maybe for those who are old or experienced will know better how to minimize losses, none other than because they already know about the various conditions that are there, so maybe when the possibility of defeat comes then they are not thinking about defeat but more focused on minimizing losses, for example they will take a break first and continue at a later time. And as you said, it is usually the beginners who will be the target of the casino.
