One third of this book was not created by me but by over 50 amazingly gifted individuals who floored me with their willingness to contribute their inspiring thoughts about the theme of subtraction. Two days before Christmas 2011, I sent notes to six dozen or so individuals whose work I’ve admired and been inspired by. I invited them to be part of The Laws of Subtraction and share their thoughts. Knowing how busy they all were, I figured I might get one out of five to participate. I was giddy with shock when the enthusiastic acceptances came pouring in. By the time 2012 rolled around, nearly everyone had said yes. Obviously, this book would not be the same without you—your additions made subtraction worth reading about. Thank you, one and all!
