This book is amazing. I came away pretty whack. On the one hand, the desire to fight against myself overconsumption, waste, waste, etc. On the other hand, when you see all it has accomplished, difficult for most people to reach that level, with the risk of frustration. Indeed, when one is a young mother with an active life, some ideas / tips may seem too inefficient (make your own makeup, their own paper ... from time to time to try / why not have fun, but routine ???). Similarly, some ideas may seem dangerous in the long run (brushing teeth daily bicarbonate?). But overall, what I get out, this is the state of mind and direction. This is already refuse to be invaded, to submit to the dictates of consumption, take care of our environment, and above all, to focus on the essential: the material is not important rather we must value the experience, the feeling, the experience, the family. A sentence has permanently marked my husband and me when the author discusses his stepfather at the end of his life, realizes that if he had something to do again, is not to "spend as much time to mow the lawn. " And just for that, I thank the author to open our eyes, and put us on this path. Read and reread.
