At the moment we win, we usually think that we can possibly win more if we continue gambling. It turns out that our mindset of winning builds strong rather than thinking that we can possibly lose. But yes, it changes everything after suffering losses and failure, and the purpose of why a gambler continues gambling at this time is to chase the money they've lost. In the end, we become a victim of our own actions from the wrong mindset and uncontrollable emotions. It can possibly happen to anyone, especially for newcomers and I believe this seems normal until we realize and correct it.
Have to agree with you, I believe it won't be wrong to say that no gambler comes into gambling with the right mindset about gambling, most new gamblers come in with the mindset of winning a lot of money and becoming a millionaire over night, but unfortunately, this is not how it is in gambling, some do get the new gamblers-luck and win a good amount of money at the very beginning of their gambling journey, but generally, gambling is not a get rich quick scheme, and so many new gamblers after realizing this stops gambling entirely, while some other who have lost good money try to see if they can recover that money, and from there, they become regular gamblers, and some even become addicts in the process.
This is exactly my story too, I came into gambling to make money and become rich, unfortunately, I realized this wasn't as easy as I thought it was, I tried to see if I could win some of the money I lost and the stop, but I kept winning little and losing more, the little wins made me believe that one day, I could win big, so I kept gambling, and till this day, I am still chasing that big winning.
