What is the author's tone in On Writing: A Memoir of the Craft by Stephen King?

The tone of this book shifts throughout the prose, but tends to be subjective on the large part. The beginning of the book is a short biography of sorts, a curriculum vitae. The tone of this section is clearly subjective as Stephen King shares some of the most personal moments of his life that he believes helped shape him as a writer. Due to the subject matter, it is impossible for the tone not to be personal.
