Everyone seems to be pushing confidence. In the world of hypnosis and in life in general. It gets people so focused on projecting that they know what they're doing that they try to delude themselves into believing it. "fake it until you make it". That can actually be helpful in some cases, but in other cases it either doesn't work or worse. I've even seen it go as far as posting on the hypnosis forums about how amazing you are in misplaced hopes that it would give you the confidence to succeed - though I somewhat doubt the kid ever even tried. There's definitely something important there, but "confidence" misses the mark.
