Telling makes it easy for the writer to sidestep emotion and dramatic tension. Telling takes the story out of scene. Writing in scene is different from describing a scene. Writing in scene combines character and action and includes dialogue and your character's inner thought. The following will help you stay in scene and show instead of tell.
Dialogue is one of the fastest ways into character.
Everyone can write dialogue. Action can be as simple as a fight. You don't need a complicated plot. Flashback can help you find out what makes the character tick. Go back into a scene from the past that informs the present.
