The world is an enormous system of different kinds of matter that exchange information. Such act is known as communication, which range from molecular levels to organizations and governments, from human beings to creatures living in bodies of water. Things communicate sometimes without being aware of doing so, just like you sometimes catch yourself off-guard, speaking to yourself in front of the mirror - you call it 'talking out loud'. Although every creature of this earth does communicate with others, human beings have a higher level of dealing with their kind, as it involves exchange of not only information, but also emotions, spirituality and others. As the person in you has the human nature to desire to improve itself in effectively communicating, as in anything, it is important for you to understand the craft first and foremost. | Conversation Skills For Beginners by Dale Blake, Paperback | Indigo Chapters
