You and I are standing this very second at the meeting place of two eternities: the vast past that has endured forever, and the future that is plunging on to the last syllable of recorded time. We can't possible live in either of those eternities - no, not even for a split second. But, by trying to do so, we can wreck both our bodies and our minds. So let's be content to live the only time we can possible live: from now until bedtime.

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.
