The first implies that stress is a bad thing, to be reduced and avoided. The reason for this strong suggestion has to do with a common misunderstanding about stress.
Most people consider it to be something clearly negative and harmful.
I recently asked a few people to name their daily sources of stress. I then asked these same people what they did to recover from stress. What this implies is that many of us either have no idea how to recover or we believe we can only do so once or twice a year, and over an extended period of time. Very few of us experience recovery on anywhere near a daily basis. And now simply find a way to remind yourself quickly of that experience so that you are again able to feel that relaxation.
