Today, beware of the impulse to get the last word in. Whether in a minor spat over who took out the trash or a business meeting where your hackles are raised, practice going inward instead of shooting barbs at people’s backs. Count to 10. Recite your blessings. Vent into a journal or pillow, if you need to. The point is: Respond rather than react. Tensions will dissipate, but words spoken in haste tend to stick.
