Talk about anything but work.
Talk to friends and coworkers all you like - just don’t talk about work.
Step outside for some fresh air.
Share a joke with a coworker, read the daily comics in the newspaper or listen to some fun music.
Close your eyes and take 10 deep breathes.
Stretch the stiffness out.
Stretch the kinks from your neck and back.
Munch an apple, drink some water or have a handful of nuts.
Play your Nintendo Gameboy or PSP.
Listen to a guided meditation.
Buy a CD with several 10-minute short meditations on it and listen to one each day.
Keep a super bouncy ball, a paddle ball (with the ball on the string), bubbles or a pack of cards in a special drawer.
Rock out to some great music.
Music is a great mood changer and just a few minutes with a favorite song can lift your mood and put a smile on your face.
