Having a positive mindset in gambling might help you stay calm and make better choices but it doesn’t actually increase your chances of winning. Gambling is mostly based on luck and no mindset can change the odds.
Staying positive can help you avoid chasing losses or making emotional bets though. So while it won’t make you win more it might help you lose less or enjoy the experience more.
Indeed, this does not have any influence on our luck, but it is important to think about those things that can influence. So our emotions can be one of the varicates, for example positive thinking is certainly good, it will not allow us to get into Tilt with losses, but at the same time we can hope that everything will be even better and we will win more, but in fact we will lose it. In general, it is better not to have emotional distortion in one of the sides, but to think about improving statium and reducing the impact of emotions on our game
Depends on the game type. in skill based games its necessary, otherwise, it doesn't make sense.
