. Have you ever heard of photo reading? They teach the idea that you are only going to get something out of a book if you have the desire to learn something from said book. You've got to want it. And you're only going to learn what you're focused on. That's why you can read a book multiple times and learn something new every time. You've got to figure out what is right for you.
And they've done a study where they found 8% of the text on any given page holds the meaning of the entire page. So really, it's 8% of the book that holds the keys. They other 92% is just filler (regardless of the author's conscious intentions). (Those numbers might be skewed. I learned this from Paul Scheele a while back so I could be a little off)
