No. Just let trigger words jump out at you and keep moving through the book at a steady pace. Ask yourself internally questions like "what about "trigger or key word"? How does it fit in with this book? Aside from the obvious subject of this book...what is the author REALLY trying to convey here? What's the big picture? Could there be an underlying message? If so, what? The more you can cultivate your curiousity, the easier it gets.
