What is the author's style in Pour Your Heart Into It by Howard Schultz?

This nonfiction book is written in the first person narrative perspective. This means that the person telling the story is the author himself and he delivers his views and relates events according to his own perception of them. The author does not supply any insight into the motives, feelings or actions of any other people and can only relate instances about these people from his own point of view. When there are conversations detailed, the author can simply relate what the other person says, and although the author may guess at the other person's thoughts, he cannot share them with the reader. Because the nature of the book is a nonfiction account of a person's philosophy on different topics, there is little room for any other points of view.
