Negotiation is part of your day-to-day encounters with people. Some learn to become good negotiators over a handful of personal experience in different situations while others still do not develop this potential within them. Negotiation is not an innate ability. It is a skill that a person needs to acquire and develop over time. You will realize that working on your negotiation skill can truly help you in many ways.
