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. Instead, this even gives them pressure and depression, leading to making bad decisions and losing more. Having a positive mindset doesn't work in gambling. It will be applied to other stuff but not in here. I could say that gambling should not be treated seriously. Otherwise, this will make your life compromised.
I gamble to win - that is the plan of every normal gambler. No one plans to lose at gambling - but losing is not entirely inevitable. Losers are allowed to lose and they just have to try again - but losing is certainly very disappointing especially when the gambler really expected to win. Here's the problem - many gamblers hope too much and they forget to think rationally because maybe at the same time they really put a lot of hope in their bet.
Having a positive mindset does not essentially make a gambler increase the chances of winning - but at least you do not come and gamble in the wrong way. Gambling is not a job that can always guarantee victory and make money - gambling is just a game, lucky you win and you will be a loser if unlucy.
