People, balance is vital. Enjoy gambling without letting it control you. You're accurate regarding financial restrictions. Chasing losses? A lost game. Unlike desperate gamers, smart players know when to go. Long-term success comes from discipline, not greed. Sometimes the wisest step is to leave, and the best do that.
This is just the summary of that people should keep in mind. Like you said, when the negative habits like you listed are removed, then there is every possibility that one will enjoy the gambling by looking at the long-term perspective. I think the longer one last in the business, the better. Those that want to beat the system overnight always end up making mistakes that distort their psychology as well as harm their finances. Anyways, everyone must not be perfect else we will wreck the gambling companies. So, the mistakes and the bad habits that lead to unbearable losses are part of what keep the business going.
Beat the system?
Casinos and bookmakers have a margin on every bet, and winnings are paid out of the lost money of similar gamblers. It is a zero sum game.
In my opinion, to win a large amount of money not only need to make a lot of effort, but also spend a lot of money and spend more than one sleepless night. In addition, you need to be born lucky, which few people do.
If you study this topic deeper, you will realize that most of the lucky ones who win big money in gambling in a few years again deprived of them, and for a variety of reasons. Some do not even need to return to gambling to lose the money they have won.
