 This book painted for me a vivid picture of the mechanics of selfish and self-centered thinking. It describes in detail the ways that we blind ourselves, especially in interpersonal communication. The result of internalizing the concepts in this book is a sort of secular elaboration of "Love your neighbor", but even though it misses (or omits? subtracts?) the spiritual core of things, it still rings quite true and the tools found in this book and others from the Arbinger Instutute are fantastically valuable.
