Stephen King: Scariest Moment

 
 
"The scariest moment is always just before you start."

I’m experiencing this terrifying moment with a novel concept I’ve been developing for about a month.

I’ve written character backstories, brainstormed a basic plot, and found books to read through to research the historical setting.

But I have no idea where to start!

How can I possibly decide where a literary life should begin? I have my character’s entire existence stretched before me (several existences, in fact, because his character arc could still go several ways).

So how, in all the infinite possible realities, am I supposed to find a perfect moment that will

  1. interest the reader,
  2. show key characteristics of the main character,
  3. reveal at least one conflict in the novel, and
  4. do everything else a good beginning is supposed to do.

It feels like an impossibly tall order. 

So here is what I will repeat to myself until I have written the first chapter:

THE SCENE I BEGIN WITH WILL (SADLY, JOYOUSLY, AND INEVITABLY) NOT ACTUALLY BE THE STARTING SCENE MY NOVEL WILL END UP WITH.

How do you get over the fear of starting?
