How This Book Is Organized

The book is divided into several chapters, organized by subject:

Chapter 1

This chapter examines ways to improve your ability to remember information ranging from the periodic table of elements to phone numbers, maps, and spatial locations—as well as how not to leave your keys and your cell phone at home.

Chapter 2

It has been remarked that we live not in an information economy but in an attention economy. If you have a broadband Internet connection, for example, you have access to more information than you could ever use, but your attention is comparatively scarce. This chapter contains hacks to minimize the demands on your attention by maximizing your ability to process this deluge of information.
