I don't see a contradiction in that. Books are knowledge. If you want to learn how to do something better - reading a book is one way to do it. Could be a video, or a longer article, but the point is the same. Another good way to develop a healthier relationship with our content consumption habits is to meditate. It's not contradictory to suggest to read a book on the benefits of meditation.
