See it from their point-of-view.
It’s easy, as a writer, to let our own POV direct our characters in a scene. Maybe some of this is inevitable. But I think good writing demands that we see from our character’s points-of-view as they’re living the story. What I mean is that sometimes I find myself being overbearing and forcing my characters to do or say things. It’s easy, when struggling, to fall into this and it almost always, at least for me, leads to inauthentic moments. Things will happen more organically and more right choices will be made if the writer can get inside his character and see the world/story from his/her POV.
Or so I think today.
