Book excerpt: Communication makes a big difference. A deeper understanding of this domain can enable individuals and professionals to achieve their intended objectives. Imparting education and corporate training in the field of communication for more than 25 years has been a transformational experience. Grappling with the realities of communication and parallel to that, conducting informal research regarding various communication principles has been an exhilarating experience. I believe that for what all I have gained while having a very interactive interface with the world of communication, now is the right time to repay by assimilating all my experiences in the form of a very comprehensive book in which the concepts and principles of communication are narrated in a lucid and non-textual manner. The objective of writing this book is to fulfill the need of individuals who need focused literature to develop their communication not only from an operational angle, like writing or making an oral presentation, but also as communication happens typically every second in formal and informal settings of the personal and working life of an individual. An attempt has been made to have an application bias instead of a theoretical one.
