You have the power to hurt a colleague with harsh words. It's best to bite your tongue whenever you feel tempted to lash out. Think back to a time when someone heaped you with harsh criticism. The last thing you want is to stoop to their level. You've reached a crossroads. You can either dwell on your anger or adopt a positive approach. Leave this distasteful situation behind and head for higher ground. Take a course that excites you. Listen to uplifting music. Make a daily gratitude list.
