The Five C’s of Negotiation Mindset
Concern for the Other Guy: Understand his position, always allow him to maintain his dignity. This isn't win/win. This is understanding and allowing your counterpart to make a deal and retain his dignity.
Confidence in Your Position and Your Ability to Deliver Value: You've got to feel good about your value and you've got to be able to articulate that value.
Consistency in Your Messaging: You must maintain your message throughout the negotiation. Any wavering and you'll blow it.
Competence: Know Your Negotiating System and Your Skills: You must have mastery of the negotiation process. That requires having a system and perfecting your skills.
Comfort Under Pressure: If you can make a deal in your underwear you can do anything. You must be able to handle any pressure in any deal at any time.
