Fatigue makes fools of us all. It robs you of your skills and your judgment, and it blinds you to creative solutions. It's the best-conditioned athlete, not the most talented, who generally wins when the going gets tough.
When you share your misery, it will not diminish. When you fail to share your joy, it diminishes. Share your problems only with the Divine, not with anyone else, as that will only increase the problems. Share your joy with everyone. Listen to others; yet do not listen. If your mind gets stuck in their problems, not only are they miserable, but you also become miserable.
