This idea also comes from the wonderful mind of my wife! To start this topic off right, and since I've begun reading The 60-Second Shrink (by Lazarus & Lazarus), I decided that everyone needs to know how to de-stress their lives. If not, one might explode! So, now it's a good idea to go through this process at least twice a day if not every few hours.
1.) Sit in a relaxed position, preferably leaning back at least a bit.
2.) Close your eyes.
3.) Breathe slowly and regulate your breathing.
4.) One by one, loosen your muscles from feet to head to fully relax and release the tension.
5.) Imagine some sort of pleasant, peaceful scene (essentially a daydream).
This simple process can take just a few minutes, but it allows you to just forget about those around you, especially the extra annoying persons you can't seem to escape. So, the next time you feel like exploding, don't. Simply go and sit back and relax a little. This will make your work environment an easier place to be.
