One of the keys to the success of a good man is that he is able to control his emotions. Not easily angry or explosive when negotiations take place a lot. Or suddenly bete when dealing with uncooperative opponents. When negotiating your emotional intelligence is tested, how to influence others under any circumstances. In addition, good self-management also allows you to recognize each side of the positive and the other person. Need to be underlined, negotiation can not be separated from communication. There's no way you can bargain just by using body language. Master the communication skills and you've won at least 50 percent of the negotiations.
