Confidence is rewarded. If someone else seems to understand the world that we don't, there is a natural appeal. As you get older, you realise more and more of the people you thought knew what was going on, don't. Some people just take better stabs in the dark. Sometimes it is luck. Sometimes it is the work of others. A little bit of delusion is a good thing. If we constantly thought about how dangerous roads were, we would probably never cross them, or get into a car. Confidence is delusion. If we are good at something, it doesn't necessarily mean we will be good at something else. It doesn't mean we know why we were good at that thing. Or if we will be going forward. What it does do, is give as the ability to pretend. Pretending gives us the back bone to take the next step.
