What is the author's tone in Wooden by John Wooden?

The tone of the book is written in a partisan point of view. Not of one particular subject but of everything in life that John Wooden believes to be true. He is even loyal to the idea that everyone should believe strongly in some belief. He says that every man should have something he is willing to stand up and fight for. He talks about loyalty, character, and the importance of family. The thing that Wooden was most dedicated to was to teaching which was the main aim of the book was to teach something he felt was very important to all who read it.
