"I", "We" and "You"
One of the most profound ways to change your posture and the way you and your organization interact with customers and partners is to change your pronouns.
Instead of saying "I" when you're ready to take credit, try "we."
Instead of saying "we" when you're avoiding responsibility, try "I."
And, every time you're tempted to depersonalize the impact of your actions, try "you," while looking the impacted person in the eye.
