Praise for A-HA! Performance"Since I wrote Choice Theory many years ago, I have come to the conclusion that there is only one major human problem: we have yet to figure out how to get along well with each other. In this book, Walker supports this conclusion with humor, creativity, and great insight. Managers who both follow his suggestions and teach them to those they manage will be rewarded with a happy and profitable workplace. And do it at less cost than the company is spending now."William Glasser, MD, President and founder, William Glasser Institute, and author of Choice Theory and Realit.
