When your colleague does a great job on an important project, compliment them on their success. If your competitor got the job over you, send a note of congratulations. Drop your guard, put down your competitive armor, and give yourself permission to revel in someone else's success. Make your words strong and reliable.
We often go through the day by the seat of our pants, counting the hours until it's time to clock out and go home. Rather than responding and reacting to whatever is tossed your way throughout the day, make a concerted effort to efficiently handle the daily minutia, and occupy the remainder of the work day thinking beyond what is in front of you.
