Do You Want To Show, Not Tell, Emotions?
Because of the way our brains are wired, readers empathize more strongly if you don’t name the emotion you are trying to describe. As soon as you name an emotion, readers go into thinking mode. And when they think about an emotion, they distance themselves from feeling it.
A great way to show anger, fear, indifference, and the whole range of emotions that characterize the human experience, is through beats. These action snippets that pepper dialogue can help describe a wide range of emotions while avoiding lazy writing. The power of beats lies in their innate ability to create richer, more immediate, deeper writing.
This emotional thesaurus includes hundreds of examples that you can use for your inspiration, so that you, too, can harness this technique to easily convert your writing into palpable feelings.
