If you're looking for a first book to get into countercultural, simple/sustainable living which reflects your personal convictions, this book is for you. One of the first written on the topic, it was produced after many of the author's friends kept asking, "So just how do you do it?" You'll get a no-bull, simply written format full of simple things you can do to start changing your life. I recommend starting with one of the suggestions and building from there. Long term habits take time to develop. You won't feel that the ideas are being rammed down your throat, just presented in simple clear logical reasoning.
As a human rights activist living overseas, this book has helped me immensely in adjusting my life to that of the people around me in the 'two-thirds' world, and staying that way when I come home.
