Whenever the narrative Point of View is first person, the story is, by definition, about the narrator. In this case, as in any writing, your goal is to draw the reader in. Therefore, if you choose to use “I” as the narrator, you need to present a quest that many readers would care about. That is true even when writing memoir. And to that end, in all cases, use the “I” pronoun as sparingly as possible. The more you use “I” the more personal to the writer/speaker the narrative feels. When you do use “I” try not to begin most sentences with I, I, I. Change-up and vary.
