Ok so i was Thinking earlier today, If I was performing for a crowd and messed up ( no worries I practice my stuff to near perfect level before I go out and perform) Which would I prefer, 1. Messing up by for example, forcing the wrong card, then during the revelation look dumb for revealing the wrong card. or 2. Messing up by exposing the method by accident, maybe a slight that was not practiced enough or a exposed gimmick. the first one makes you look bad but protects the secret behind the trick as where the second one reveals the method, but might give you some credebility by doing something they see as being very well thought out or something that takes a lot of time to learn. I personally would rather look dumb myself, then give the method away even if I did get a bit of credibility out of it. Im not saying you should not practice your effects, Because I think you should be able to fool yourself in the mirror before going out and performing, but a mistake can happen, we are only human. so which would you prefer?
