When you are always under tension, you know that something is going on. One of the environments where we often feel the most tension is at work. In the work place, we strive to live up to some imagined set of criteria. We put tension on ourselves. In some cases, the tension comes from time deadlines, or from instructions that are unclear/ambiguous. We have all felt this tension.
To move away from tension, we need to find ways to relax. For some, listening to music accomplishes the ideal relaxation. Others need laughter or some sort of fun. Still others need to leave the office and go for coffee.
There is not one right way to relax. You simply need to find what works for you.
