I assume that people come to the gambling industry as inexperienced people. And in the process of their activities, they gradually learn from their mistakes. Unfortunately, some of these mistakes are dramatic and cause us quite serious psychological trauma. As a rule, this is due to gross errors and stupid persistent beliefs that push us to the edge of the financial abyss.
First of all, this is risk management and money management. The second is probably unsystematic play. Let me make a reservation that I do not mean casinos, as well as people playing "for fun". I mean sports betting.
So, how much did your mistakes cost? Did they cause you a serious psychological blow? What were your mistakes, did you learn from these mistakes and do you apply this knowledge in practice now? Were these mistakes simply painful, dramatic or catastrophic?
I think in sport betting mistakes do not cost as much as the mistakes people make when playing slot machines. There is that saying that goes, experience is the sum of all errors that we make as the only people who do not make mistakes are the people that don't do anything in life. Personally I have been doing a lot of mistakes during my gambling years and luckily I have been far from catastrophic though some dramatic ones I have commit. I have learned a lot from such mistakes and now I am not gambling that much anymore thanks to such mistakes. So overall mistakes are not that bad when we learn something from them and we put those lessons to good use. From what I have learned in slots is that they are not truly random as they are advertised rather they have some patterns which they abide by.
