"Kill your darlings, kill your darlings, even when it kills your egocentric little scribbler's heart, kill your darlings."
Stephen King.

A dramatic quote from someone who really knows how to tell a story.
Many manuscripts land in our in box and, sometimes, I want to send the writer this quote from Stephen King. We know that writers grow close to the characters they create, and their instinct is to protect their creation. But...the characters are there to make the reader's heart race with anticipation or slow with empathy.
Let's think back to the first stories we are ever exposed to - would Red Riding Hood have captured our imagination if the wolf hadn't eaten granny and dressed up in her clothes? Would Hansel and Gretel have been so dramatic if the stepmother had seen the error of her ways and decided to tolerate the children? 
No, we need the threat of our worst fears!
Writers, be brave, go for it!
