A Pause for the Cause
Don’t get mad, don’t get even, Get What You Want.

Pause and breath. You can’t unring a bell. Don’t say things when you are hot that you will later regret.
A barrier to negotiation is your natural reaction to: Strike Back, Give In, or Break off.
Suspend that reaction and regain your mental balance. Stay focused, Pause and breath. Don’t get mad, don’t get even, Get What You Want.
Never split the difference.
