You know that moment. You’re in a meeting (or worse, on stage) and someone says something that hits you right in the solar plexus. Your face heats up, your heart races, you feel rage, or fear, or embarrassment, or sadness—pick your poison—and before you know it, you’ve missed the last 3 minutes of the meeting, lost in your own reaction. If you’re someone whose default reaction is to fight back, you consider your counter-attack. Or your default reaction may be to get out of the meeting as quickly as possible, and stay as quiet as possible in the meantime.
Either way, from my perspective as a communication coach, you are in a death spiral. Once you go into default-reaction mode, it is unlikely that anything good will come out of your mouth.
