Before I drift further away from Jerry Harrell's original point, I wanted to mention that I am the daughter of a (retired) professional photographer, and it's very true that the majority of that stuff never made it past the contact sheet phase. As for my own magic, I have worked on and plotted out and put together far, far more things than I have ever presented to actual people. And I know that Michelangelo routinely destroyed his prepatory sketches and rough ideas, because he only wanted the impression of perfection to remain.
Now for the promised drifting. I don't think that becoming a pro is necessarily the mark that proves a person's passage through magic was worthwhile. I remember reading a great David Bowie quote, where he said he felt that "David Bowie" was just the aggregate of all of the people who were thinking about him at any given moment. Magic, at any given moment, consists of the people who are thinking about it. The whole is greater than the sum of its parts, but it needs parts to exist. So in that respect, magic club goofballs are every bit as vital to its life as the leading lights of the art. (And when I say "magic club goofballs," I invoke the well-known dictum that you are allowed to make fun of what you are.)
