The important thing in conversations with difficult people is body language. You can’t send a firm message while your body is sending signals that you are being passive.
Find your tone of power.
Here’s how you do that: simply look down at your feet and go, “Mm-hmm.” This sound should be resonating, strong, and firm. When you vocalize it, you need to speak in a slow and steady tone.
Keep your head straight—don’t tilt it.
That’s what dogs and other pets do when they want to show you they are playful and harmless.
Maintain eye contact.
In normal conversations, you don’t want to maintain eye contact for longer than seven seconds. During difficult conversations, you should maintain it much more intensely.
Get rid of physical things standing between you and the person you are communicating with.
Physical obstacles contribute to conversational barriers.
