This is the third book in the Happy and Successful series, focusing on relationships. In “Harmonious Relationships” , Andy Shivaram proposes an approach to relationships and marriage that will keep the mood music as melodious as possible and maximise the chances of long-term success. The first book, “Climbing your Life Tree” , was about improving oneself, where the author shared lessons on how to maximise life’s potential with those wanting happiness and success. The next book “ Flourishing Child ” described the actionable strategy needed to bring children up and give them the best start in life, to maximise their fulfilment and avoid them having to learn things the hard way. The fourth book will be on work-life. Taken together the four books aim to provide a holistic, no-nonsense recipe for being happy and successful across the many areas of life.
