I've been hearing that confidence is the most important because it shapes the perception that you are more worth than you look. If so, how does one fake it? I never did that because I thought being over confident would conflict with what I represent on the first glance, which will make me look like a scammer of some sort. Even if not, I never had an ability to just immerse myself into someone more successful that I am at the moment. How important is confidence and how far can you go with it?
