A lack of satisfaction and high expectations is what makes some gamblers to still continue playing after having a win that was supposed to be taken as the achievement of the day but they get unsatisfied with the amount bethinking that maybe if they could try another bet again it might get them lucky to win again but it most times ends in loss. For the fact that I was lucky to win ones or probably twice at a row doesn't make it certain that I might continue in the winning streaks. Sometimes that one win after many times of losses for the day is just fortune own way of smiling at us so we don't go back home completely emptied.
Yep, a gambler who gambles only to earn money from it barely gets satisfied with the winnings no matter how big the amount they've won is, they will always try to increase their winnings and in that pursuit, they lose what they've won if they aren't wise enough to stop at the right time and in most cases, greed takes over the mind of a gambler who is gambling just for the sake of profits and don't consider gambling a source of entertainment or a time killer for them.
People who are gambling for gains and have been losing constantly don't consider a win to be good enough if it's insignificant to cover all the losses they had to bear so far because they would want to recover their losses before they end the session but in most cases, they end up losing everything which will be the end of the session for them.
If we discuss something in terms of hopes and desires then obviously it will always have no end, as happens in real life, usually we have difficulty in choosing about what is actually needed and what is wanted, often we are fooled because of these two things that usually unconsciously we prefer desires that basically do not really have a positive role / impact on our lives. It's the same with gambling, when people have high hopes following the desire to get something bigger then obviously they will prefer to increase the risk when in reality they can't accept all the consequences if they end up losing.
So in my opinion there are only two things that have the possibility to stop it, namely awareness and regret, realizing that everything they do including the mindset they carry is wrong and only makes them worse and with that incident there is some potential that makes them feel regret. If you gamble with high hopes and desires then obviously it is not entertainment that you get but a lot of pressure and new problems that arise because you are wrong in understanding the real gambling.
