I'm not a novelist, but I do write a weekly column for my college newspaper. I almost always find myself compelled to read my column once, just to see what it looks like in print. I invariably find things I don't like about it--turns of phrase that I would change if I could, a new way to structure my argument, etc. I can usually never bring myself to read the thing again. But I always feel compelled to read it in print once.
(Of course, a 500 to 800 word column is very different from a short story or novel.)
