In my view, placing new bets requires a clear mind, not belief in miracles. Or rather, being calm enough and not too emotionally invested in hoping for a big win. Still, for many people, that belief is exactly why they play. Some change their approach, others stick to their “trusted” methods — but both face the same thing: chance is stronger than expectations.
So as long as there's a sense of joy in the process, and an ability to control one's budget and not get in trouble with losing too much money, it's okay to do whatever feels right for a particular person. I don't think it affects the chances of winning, but it can improve one's mood and help focus on more positive moments, which is a win in my book.
You think exactly like me: if you're having fun and keeping your cool, you can play as long as you want or have the cash to do so, without high expectations.
If you win, good, if you lose, good too, with that little disappointment of not having won anything.
But in your mind, you already think that next time will go better, or at least you hope so.
Gamblers should definitely try to understand these things, I never play with high expectations, because I know that the higher the expectations, the greater the disappointment. Although I gamble very rarely, I try to gamble as accurately as possible and with all the limits set, and no matter what the result is at the end of the game, I have no sadness or disappointment, I accept any result. However, other gamblers should also gamble with this reality in mind, gambling is a matter of luck, so there is no point in getting excited here, but getting excited and making the wrong decision here means only leading yourself towards disaster.
