I got this from a retired SF guy. Incredible individual but I would not want to get on his bad side.
One of my favorite "after" combat lessons, attributed to a retired female army combat nurse (Colonel).
Lessen the Stressin'
Ah, stress relief. Picture yourself near a stream. Birds are softly chirping in the crisp, cool air. No one knows your secret place. You are in total seclusion from that hectic place called "the world." The soothing sound of a gentle waterfall fills the air with a cascade of serenity. The water is clear. You can easily make out the face of the person you're holding under the water.......... There now ... feeling better?
