This paper will present basics of communication, importance of knowing appropriate way of communication in business environment, how to accomplish a competitive advantage in business, and also what body language can tell us. Aim of this paper is to revive importance of knowing nonverbal communication in everyday activities, whether you have a conversation with a salesperson in a grocery store or with a work team where a new idea is being presented. By using many sources of different authors through this paper and by finding general conclusions, a method of abstraction and of synthesis has been used. To accomplish total control of nonverbal communication is not possible because of many unconscious activities and micro signs which reflex automatically on minds command. By learning this skill a person becomes more aware of itself and is capable of increasing other connected skills, for example negotiation. The first impression is made in less than four minutes through conversation and it stays as a permanent opinion about a person. By developing nonverbal communication, a person directly increases possibility of leaving a positive first impression. This paper is for all people who are willing to develop a new skill and for all who want a better understanding of what the body tells us during a conversation or when a verbal communication stops.
