I honestly believe that this is one of the greatest secrets to true peace of mind -- a decent sense of values. We could annihilate 50 percent of all our worries at once if we would develop a sort of private gold standard -- a gold standard of what things are worth to us in terms of our lives.
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.
Dale CarnegieMen of age object too much, consult too long, adventure too little, repent too soon, and seldom drive business home to the full period, but content themselves with a mediocrity of success.
