Then, what do you know about the character you are focusing on for this exercise: his or her place in history or life? Do they have a position of influence? Are they bound by their place in the culture of the community where the action occurs? Or have they been influenced by the events that impinged on life before the story opens?
The point is both scenes and chapters have a place in your story’s pacing. Short chapters tend to move the action along quicker. Longer chapters might lull you into relaxing with the longer flow of information and less tension. Remember, both scenes and chapters have a part in how quickly your story unfolds, and how your reader experiences the story.
Even if you are writing a memoir or biography, it is important that your work has a plot or spine that holds all the bones together.
