Writing vs Storytelling
Writing and Storytelling refer to everything that revolves around the creation of a story, such as brainstorming, drafting, and editing.
Writing and Storytelling skills are not the same thing when it comes to writing a story. However, they do affect each other, and it's important to recognize which skill you have more strength in and which skill you would need to work on. To identify which skill is your strength and which is your weakness, you will have to look at your writing.
Writing skill is more technical. This is concerned with literary techniques such as sentence flow, diction, and structure. Signs that writing skill is more your strength: -You probably experience frequent writer's block of not knowing what to write or where to go with it -You're good at explaining ideas -You prefer to plan/outline stories -You find more issues with concepts as you edit -You write more detailed descriptions and have a good literary techniques
Storytelling skill is more conceptual. This is concerned with plot, meaning, and entertainment. Signs that storytelling skill is more your strength: -You probably experience frequent writer's block of not knowing how to write something -You're better visualizing plot points than describing it -You can come up with ideas and concepts on the fly -You struggle with not enough description and too much plot -You better understand cause & effect and tension
Just because you may have a strong skill in one and not the other does not mean you're a terrible writer, but knowing which one you exceed in can be the first step towards finding better resources for what you need to improve on and what you excel in.
