You just had a conversation in which you agreed to do something. You made a commitment. How do you want the other person to feel, as they walk away from you?
People often tell me how much they need to be able to count on one another to come through, particularly during this period of doing more with less.
Think about it for a moment. When you do what you said you’d do, you give people concrete evidence that you can be trusted. Trust is your relationships’ adhesive. Without it, everything gets harder and takes longer.
