This companion content includes over 60 pages of supplemental material spanning each chapter of the book.  

 

These additional design tips, stories, social science, and more were edited out of the original manuscript for brevity -- but are perfect for those craving more detail and insight.  

 

Designed to go hand-in-hand with the book, chapter and page number notations tell you precisely where these companion sections fit topically and thematically.  

 

Unlimited access for one-time fee of $25.
