Olivier Clerc is known for his art of writing images that even children can understand, but what seems to be a treasure in the literary world, it is above all the clarity of his remarks. Behind this apparent simplicity, we discover very quickly an incredible lucidity and sharp analysis on all topics, social facts to the smallest details of our daily lives. Here, he invites us to dive into our inner world to do the cleaning. But suprenante thing he does not come to tell you to throw and even less what to throw, but how revisit and classify all you have packed, thanks to 4-stage sieve, and especially how to become the only master on board . Personally, since reading this book, my conversations have increasingly often, the screen in the background, and what a treat!
