It is impossible for a person to earn from gambling and leave it for the rest of their life.
Beginner's luck is the most tempting kind of win. The gambler, if not conscious, can get trapped in gambling, and it becomes difficult for him or her to quit when there is still hope in their mind of winning again. Gambling can be a never-ending storm for those who cannot control themselves.
So true, mate. The beginner's luck is the first step that traps you in this system, and once you enter, you will know that the exit is very difficult. At the beginning stage, when you are winning, you will think that you can do it, and honestly speaking, that first win is the profit that motivates you so much, and your destruction starts from it. If I can simply say, it's a loop where you can get stuck easily, and you will put your hard earned money into chasing nothing.
The only possible way is to accept and realize that gambling is not a quick rich scheme and to work the way it is showing. Once you realize this, then the exit will be easy for you.
