In that you are right, so when I was a newbie and I played a lot of dice that feeling always appeared, so when I was playing and I lost I always thought about what I could buy and that filled me with rage at myself, of course that is a thing of the past, now I do things differently, not with the same intensity, now things have changed and are seen from another point of view, a more mature point of view, where my secret is in putting up the money to lose in a casino, I don't put up more than that money because that throws everything off, so I think that all those mistakes, feelings and things that I went through helped me a lot to mature my game.
Good for you, most people don't learn from their mistakes and they keep repeating the same mistakes again and again, especially in gambling. You will often see gamblers losing a lot of money in gambling, they may feel bad about it and curse the casino and themselves due to the heat of the moment, and they might even stay away from gambling for some days, but after a few days, you will see them gambling again, and if you ask, they will smile and say they couldn't help it.
Most times when the foundation of your gambling activities are not solid, you tend to loose yourself more and more, even after heavy financial loses. Its not that those dudes are not learning from their mistakes, its only that they are unable to control themselves from gambling. there is a stage your addiction would reach, gambling would be an inseparable part of you and you cannot feel good unless you gamble. At this point, that gambler needs help because left alone, they can do nothing at this point.
For me, I have also changed a lot. When I first started gambling long time ago, I had no control, I used to use strategies such as martingale because I used to think they work and you can recover your lost money or points by doubling your bet after each loss, it used to work sometimes, but pretty soon I realized that it is nothing more than a disaster strategy.
Strategy without gambling in moderation is futile, soon enough the person would understand that the most productive thing to do for yourself is having a gambling budget first, then with the budget you can go ahead to test all strategies available to you and still not get hurt provided you do not exceed your gambling budget.
