How effectively it is done is the issue, and this is not always easy. Communication skills are learned. If we grew up in an environment of good communicators, we learned to interact positively with others. If we did not, we can have a lot of difficulty. One of our greatest sources of stress in life comes from having to interact with other people.
Effective communication is central to our ability to get along with others.
We are social beings and it is vital that we know how to communicate effectively. Respect for self and respect for the other is the foundation of effective communication. It is difficult to have good communication between people when one is perceived to have more power than the other. On one end of the communication spectrum we have the aggressive, bully types who tend to promote conflict as a way to get their needs met. On the other end we have the passive, timid types whose goal is to avoid conflict at all costs.
