Agazarian defines communication as "the medium through which people in groups relate to each other as people," adding that communication is "the method by which decisions are made affecting the group's social and working life" (Agazarian, 1968). How important it all is, and yet typically we communicate without active thought or consideration!
Regardless of our level of cognizance, our words always have immediate and consistent impact. Yet the intentional practice of communication skills, a seemingly excessive exercise considering concerns that dutifully throw themselves in front of us on a daily basis, is rarely undertaken despite the far-reaching effects communication has on the lives of self and others.
How the process of day-to-day living could improve if one were to be disciplined enough to intentionally develop personal communication skills on an ongoing basis. The idea that communication and the quality of life are fundamentally connected, where improvement of communication skills directly improves the quality of life, doesn't seem too far a stretch.
