To make the reader feel the anguish and turmoil, pain and internal struggle going on within a character is key. How to you go beyond their heart racing, their hands sweating, their legs trembling? Where do those panicked thoughts come in? When do you make them suck in a desperate breath, rake a hand through their hair, or let their eyes slide close?
Sometimes I watch a movie and I wonder, how would I write that scene? I often find myself describing it--typing out the emotions that the characters are feeling that play so eloquently across the screen. But the movie characters don't tell us they are scared or hurting. We see it! Readers don't want to be told, either. They want to feel it. The art of being a spellbinding writer is finding the ability to make the words come to life as easily and effortlessly as if the reader were watching it as a film.
Watch this scene. How would you write it?
