Some of the more obvious things about life are often overlooked. We're born, but can't recall being asked to be born. We're alive and soon we are expected to take care of ourselves in nearly all aspects of our lives. When we're born we have no language skills and we don't know most of the rules for successful living. We are wholly dependent on others for most things until we finally are "allowed" (another word might be "forced") to assume responsibility for living a life we didn't ask for in the first place.
Looked at from that point of view, life might seem bleak. On the other hand, there are a great many things about life that are fantastic. If we are willing to learn how many of them are achievable during our lifetime. Most of what we need is the indirect support of others who are in the same position we are. It can be argued that a successful life is made up of learning and adapting.
Communication in all its forms is at the heart of learning and adapting. In fact, being able to think is heavily dependent on communication. As we move through our lives we need to be able to let others know what is going on inside of us and allow them to see what is going on inside of them. In a very real sense, we are trapped inside without communication skills. As our skills increase we gain more and more freedom from the restrictions our bodies started off with at the beginning of life. Communication is worth any time and effort we can spend learning and practicing. Learn and apply until we're dead. The other choice is to remain captive, trapped inside.
