How do you need to think correctly before going to the casino in order to absolutely have fun and have a good time? You need to allocate a certain amount of money. And say to yourself, "today I can lose it, so mentally I say goodbye to this money." You need to go only for emotions and in no case for a win. And even if you lose everything, you will say to yourself, "It's okay, I got a lot of positive emotions, this is what I came here for."
Well, if such a player wins, it will be an excellent and unexpected bonus. That's the right way of thinking should be.
That might be the right mindset for someone entering a casino for gambling but most people don't have that mindset when they start gambling and they barely see it as a fun activity but most of them enter the gambling space only to gain multiple folds of their money which is their main target and they lack the understanding that it's not possible for everyone to actually constantly earn money from gambling because casinos are businesses and businesses are created to earn money for their owners and not their customers.
The wrong mindset of gamblers makes them lose a lot of money, they first try and win some money with what they have, and once they lose a part of their own money, they start trying to recover that money which further makes them lose more of it. They might be able to successfully recover their losses once or twice, but if they try it more, they will end up losing everything.
