1. Tactical Empathy: It's not about feeling their pain, it's about understanding their perspective and emotions. Mirroring their words and acknowledging their feelings builds trust and creates a calmer environment.

2. Label emotions: Validate their feelings by naming them (e.g., "That sounds frustrating"). This diffuses tension and encourages them to open up further.

3. Silence is your tool: Don't rush to fill the silence, use it strategically. Let them fill the void and reveal more information.

4. Calibrated questions: Ask open-ended questions that elicit further details and uncover their needs and priorities.

5. The two magic words: "That's right." This simple agreement validates their perspective and keeps them talking, creating opportunities to shift the negotiation to your favor.

6. Bend their reality: Use stories, metaphors, and reframing to subtly influence their perception of the situation.

7. No deal is better than a bad deal: Don't be afraid to walk away if the terms don't align with your priorities. Leverage is key.

8. Find the "That's right" moment: Summarize their perspective accurately to gain their agreement and reiterate with "That's right" to solidify trust and control.

9. The Black Swan: Introduce unexpected elements to surprise and shift the momentum in your favor. Think outside the box.

10. Guarantee execution: Ensure any agreement comes with clear steps and accountability measures to avoid misunderstandings and ensure follow-through.
