Here's something you can use today...
Next time you're frustrated with someone, try this before you react:
Instead of saying what's wrong with them, name what you need.
"You never listen to me" becomes "I need to feel heard right now, can we slow down?"
"You always make it about you" becomes "I need this conversation to be about both of us."
The complaint puts them on defense. The need invites them in.
Try it in your next conversation — even a small one. What happened when you said the need instead of the complaint?
