The authentic details you identify when writing the scenes in the Beginning (1/4) show the objects the protagonist most identifies with. These objects reflect the protagonist's conditioning by her environment, upbringing, and culture.
When the protagonist moves into the Middle (1/2), she moves out of the ordinary and conditioned world into an exotic and unknown world (thus, the need to create two unique settings).
Whether she is a willing adventurer or resistant is reflected by the degree of pain caused her by the loss of these objects. Unable to base her identity on her association to her things and lifestyle, she questions who she is. Thus begins her inner plot line and creates the 1st step toward the incremental and ultimate story transformation.
Look at the objects surrounding you. What do they convey about where you are on your writer's journey? What can you let go of and move closer to where you wish to be?
