This should depend on the gambler in specific, because some of us got to gamble because of this same instinct we've got from anything we are more convinced about, then we try to test them by gambling and know about how capable we've become to predict and guess right, sometimes as well, it may come as a test on us, to know how we could perform in gambling, then we make some decision base on the influence of what we are gambling about.
We've got instincts that we should bet like a YOLO mentality and sometimes that gives us good ending. But that's only a rare situation that we don't know if it's going to happen again or not. I think all of us gamblers have one thing in common and these instincts that we have sometimes are correct. When we feel that the last bet is going to make a turn around positively for us, we're doing it. And yet, for most of the time, it turns out that it's a bad instinct that makes us lose more instead of winning because we're too confident to ourselves.
