No one likes to feel that he or she is being sold some-thing or told to do a thing. We much prefer to feel that we are buying of our own accord or acting on our own ideas. We like to be consulted about our wishes, our wants, our thoughts.
Dale CarnegiePsychiatrists declare that most of our fatigue derives from our mental and emotional attitudes... What kinds of emotional factors tire the sedentary (or sitting) worker? Joy? Contentment? No! Never! Boredom, resentment, a feeling of not being appreciated, a feeling of futility, hurry, anxiety, worry-those are the emotional factors that exhaust the sitting worker, make him susceptible to colds, reduce his output, and send him home with a nervous headache. Yes, we get tired because our emotions produce nervous tensions in the body.
