1. No one wants to see your drafts, except (maybe) your writing group.
2. If you’ve written a book, and you want to show it to someone, make
sure it’s a brand-new, shiny copy and not your beat-up personal one,
or they will look at you as if you’re a homeless person. People really
do judge books by their covers.
(edit) Reword rule 1 to “No one wants to see your drafts, except *your editor* and (maybe) your writing group.”
