Nobody Wants to Read Your Sh*t by Steven Pressfield
There's a mantra that real writers know but wannabe writers don't. And the secret phrase is this:
NOBODY WANTS TO READ YOUR SH*T.
Recognizing this painful truth is the first step in the writer's transformation from amateur to professional.
From Chapter Four:
"When you understand that nobody wants to read your shit, you develop empathy. You acquire the skill that is indispensable to all artists and entrepreneurs--the ability to switch back and forth in your imagination from your own point of view as writer/painter/seller to the point of view of your reader/gallery-goer/customer. You learn to ask yourself with every sentence and every phrase: Is this interesting? Is it fun or challenging or inventive? Am I giving the reader enough? Is she bored? Is she following where I want to lead her?"
