Which child grows into a happy adult? Is it enough for a child to have a joyful childhood? Or does it all depend on what is written in the family? Then, can parents help their child “write” happiness into their own family? Or is their main task not to interfere? And what is happiness, finally? Perhaps it seems to you that life is not enough to answer all these questions. The authors of the book do not think so. Moreover, they are confident that it is possible to raise a happy child who will become a happy teenager and then a happy adult. It may not be easy, but it is possible. How? They talk about this in detail in the book.
