This is a constructive book. This book is about a person whose life is totally messed up in daily routine. Day to day lots of questions come to his mind but he never cares to find answers to those until he meets a random guy who changes his whole perspective and helps him identify the answers within his own questions. This is a dialogue based story which humiliates and challenges our thought process but completely changes the notion which 97% of the population carry within themselves.
This book may help you establish correct goals for yourself and find the importance of WHY over HOW.
