I agree with Alpster's take.
I chuckle inside when I hear someone say, "You've got to have confidence!".
That to me is like saying to a starving man, "You've got to feel like you've just finished a meal".
Simply put, "confidence" is something that follows, it does not lead.

Interesting thread, and Roger as always you make a good point, but in this case I respectfully disagree. I believe it is confidence that keeps you focussed, and attentive to what you know from experience works. It is not to say , "You've got to feel like you've just had a meal," to a hungry man, but "Trust me brother if you do what I'm doing, we'll eat soon." While cofidence begins with success it is more than that. It is an assurance that what I'm doing is right, even if it isn't working at the moment. Just my .02
