Your ability to control your signals can have a profound impact on a negotiation.
The body language signals what you convey, along with what you say at the beginning, influence what happens during the negotiation. They set the tone for what follows.
When you use body language, you have to be very astutely aware of how your being is perceived.
Here's where emotional intelligence also comes into play. Always be willing to walk away from a negotiation. In so doing you will be insulating yourself from staying engaged in the negotiation if by chance you are below the lowest offer you know you can accept. Calculate what you're going to walk away from. Be willing to tell your opponent, "This is not going to be satisfactory for us today. How about we reconvene later?"
You can gracefully get away from the negotiation, but the one thing you don't want to do is berate the other negotiator. Always leave the negotiation door at least cracked just a little bit so you can go back in and reopen the negotiation. Don't burn any bridges.
