“ The typical image of a depressed, lazy and tired person is someone hunched over and inert. Often, the assumption is that if one had more enthusiasm and inspiration, he would then stand up straight and move. In many cases, this equation is backward. But, as with everything related to one’s physicality, balance is the key. An overly erect and rigid posture may convey confidence and power to some, but it also causes a subtle accumulation of tension and rigidity on various levels, including psychological and emotional. ”
