1. I greatly enjoy non-fiction books which include the author's perspective, as it provides a deeper layer of story-telling which often makes the topic more captivating and relatable. I don't believe it is self-indulgent to include yourself in your work, especially if it helps propel the story.
2. Useful, relatable, perspective-shifting, honest non-fiction is my favorite kind. I enjoy reading about a person's personal hero's journey of self-discovery and exploration.

Thanks for prompting this self-reflection and for sharing your process. Your writing resonates with the kind of work I'd like to create.
