Reason #1: You Don't Buy Books

How many books have you bought in the last five years?

Make a rough guess. Now eliminate anything in the following categories:

non-fiction

gifts

remainders

second-hand

(ghost)written by a celebrity

published prior to 2001

(If your total is already down to zero, give up any fantasy of being a published writer. Right now.)

Keep going and eliminate:

established authors (prior to 2001)

anything with "Bestseller" or "Oprah" printed on it

recommended by a friend/family member

anything by an author you know personally

If you have a few books left, congratulations. Check back for Reason #2.

If you haven't taken a chance on a new, unproven author in the last five years, why the hell would you expect anyone else to?
