I used to go through my textbook page by page. I was trying to make sure I understood all the ideas before I turned the page. Sounds sensible, right? Don’t do this! It was a big mistake. Instead, when you start a new chapter, go on a “picture walk”* through it. Scan it. Look briefly at all the pictures, captions, and diagrams, but also at the section headings, bold words, and summary, and even questions at the end of the chapter, if the book has them.
