Despite several losses happening, winning is always on the mind of the gamblers. That is why they are still here and continue gambling. However, despite being too positive, they still lose. Why? Because it won't change the situation, nor will it attract luck for them.
Having a positive mindset doesn’t set the odds to a bet, it might only slow you to be more realistic and analyze your bets critically so as to increase your chances of a win but that’s mainly in sports betting.
However, the positive mindset would keep you gambling and you must be sure not to loose yourself in it and let it transform into addiction because, there you would find a real problem of your hands, needing to resolve and it wouldn’t be easy.
