This book is about parental authority in modern times and its pivotal role in raising self-reliant, compassionate, and ethical children, and in preventing behavioural and even severe psychiatric disorders. The last generation witnessed a backlash against disciplining children. We as parents are told to engage in negotiation with our kids about their behaviour. We are afraid to be tough with them in case they will not love us or worse -- breakdown. As a result, families today face severe behaviour problems at earlier ages, and parents throw up their hands in resignation. The main theme and objective of this book is to prove that setting and enforcing reasonable and appropriate boundaries, combined with learning and education, could save parents' relationships with their kids and literally save childrens lives. The book is unique in that it presents in a direct, simple, and yet profound way, real case studies and situations commonly encountered, along with severe cases of drug abuse, delinquencies, and mental disturbances. All cases are shown to respond very well to authority and boundaries adjusted to the specific situation and behaviour. The book contains numerous references to professional material for the more advanced reader and derives inspiration from ancient philosophers and religious thinkers.
