Show, not tell. That’s a very old writing tip that a lot of new fiction writers, myself included, fail to implement when starting out with their journey to writing stories and novels.
I learned, however, that it’s not because we don’t know how to write. Rather, it’s because we were trained to write this way in school, most notably with nonfiction. Well, in nonfiction, telling is the way to go.
In fiction, it’s another story.
If you want to raise your story quality by a bar or two, it is very important that you be able to grasp the concept of how to show action, instead of telling.
