Life is a flow of different experiences. In fiction we frame it: beginning, middle and end. A character exists in a maze facing a series of obstacles; not too many, not too few.
To simplify plot, think about a character wanting something and someone or something getting in the way of that. The story involves the "and then whats."
Three basic plots exist in the conflict situation: man against man; man against nature; man against himself.
Consider the underpinnings of story as character, emotion, situation and setting. The challenge becomes what to put in the middle as a tent pole.
