Psychologist Henry H. Goddard conducted a study on energy levels in children using an instrument he called the ‘ergograph.’ His findings are fascinating. He discovered that when tired children were given a word of praise or commendation, the ergograph showed an immediate upward surge of energy in the children. When the children were criticized or discouraged, the ergograph showed that their physical energy took a sudden nosedive.

            You may have already discovered this intuitively. When someone praises you, doesn’t your energy level go up? And when you are criticized, doesn’t that comment drag you down? Words have great power.
