I’ve done speed reading since I was in school. I make a speed game of flipping through each page, quickly noticing each headline, picture, caption and boldface until I’ve physically leafed through the entire book.
Then I go over to the index and scan it quickly for something that ‘jumps out’ and then I go to one of the indexed pages and start.
In lieu of that, I read from back to front. Reading from front to back is almost physically painful.
