The Unfettered Mind Paperback – Deckle Edge, 12 June 2012

My review of 'The Book of Five Rings' apply to this book as well. It is among the 4 classics on strategy that I carry with me at all times. I prefer the print version because I tend to annotate the text with my observations over time.Required reading for the most refined study of strategy (business, marketing, martial art, war, politics, or anything else that can be interpreted as conflict), along with Sun Tzu's Art of War, Musashi's Book of Five Rings, and Lao Tzu's Tao-Te-Ching.
