Viewpoint or Point of View is extremely critical to your story. The Point of View allows the reader to experience someone else’s view of the world. The POV often determines whether a story is successful or not.
Multiple Person Viewpoint is in my opinion the most flexible (and hardest) viewpoint for the author to use. That flexibility is a valuable asset for the author. So don’t shy away from it.
This is essentially “I”, “Me”, “Mine”. The POV is from the speaker. He/She tells the story from His/Her perspective.
