There are people who have had unpleasant events in their lives, and therefore such people are not good at controlling themselves. And I can assume that if this had not happened, they would be calm and balanced in their decisions. But such people are often found in gambling, and they absolutely do not know how to stop gambling and say to themselves "enough".
Well, my perspective is different. When something bad happens in a person's life, they should learn from it and even behave better. This is because what he has gone through in the past is supposed to serve as a wake-up call for him, as well as help him shape his life better. People who have lost a lot of money through gambling are expected to be even more responsible gamblers as a result of their previous experiences.
Gamblers who have lost a lot of money should learn how to stake a small amount of money, understand that gambling does not make you rich, and understand that you give more than you receive when gambling. These are the things a gambler learns after making a mistake, and in order to avoid making the same mistake again, he learns self-discipline and control in the hard way.
For a newcomer or someone who has not done it before, he can easily fall into the trap of losing more than necessary due to impulse gambling, regardless of advice he may have received online or from people close to him. Most gamblers gain experience before they learn.
