Over-Confidence

Confidence is actually a fairly amorphous trait.  You know when people are confident. You think you know.  But their internal world may not coincide with what you think you know about them.  Likewise, I could know when I'm confident, and also be cripplingly insecure at times.

Anyway, the point here was supposed to be that drinking obviously leads to over-confidence, but that over-confidence can be particularly insidious. At its most extreme, it is delusion.  Without any confidence, though, deep depression takes over.  So I no longer have a post.  I am not the right person to ask such things!
