That's a statement not really a purpose. A purpose would explain to me why you want to do that.

So, Why?

Does the book teach strategies and techniques you need to apply? If so with traditional reading you would need to re-read sections of that book again and again. It sounds like a book that is more than mere reading it's teaching you something that you hope to teach. Whenever someone sincerely wants to learn something that they want to teach others they will spend more time with the book. If you were only interested as a passing fancy then you would merely passively read the book pick up one or two ideas that you might just pass on to your child.

What is happening here is you have a greater purpose than just reading the book. It requires some self training if my impression of the book is correct. So go easy on yourself. I see some great progress with your PhotoReading skill.
