I think this is just about normal for most gamblers to really think positive when they play and that the next outcome of the game will be favorable to them. But in any case, this could also be very bad because you might think that being positive will be enough which is very wrong. And then you might go for another set, let's say in a roulette and bet either black or red.

One more try and that's it. But then again, after you win, you are going to continue and play and that positive mindset will push you. And then after that, you end up losing everything you have. So we really need to think logically.
