Sooner or later, a man, if he is wise, discovers that life is a mixture of good days and bad, victory and defeat, give and take. He learns that it doesn't pay to let things get his goat; that he must let some things go over his head like water off a duck's back. He learns that carrying a chip on his shoulder is the quickest way to get into a fight. He learns that buck-passing acts as a boomerang. He learns that carrying tales and gossip about others is the surest way to become unpopular. He learns that giving others a mental lift by showing appreciation and praise is the best way to lift his own spirits. He learns that the world will not end when he fails or makes an error; that there is always another day and another chance. He learns that listening is frequently more important than talking, and that he can often make a friend by letting the other fellow tell his troubles. He learns that all men have burnt toast for breakfast now and then, and that he shouldn't let their grumbling get him down. He learns that people are not any more difficult to get along with in one place than another, and that "getting along" depends about 98 per cent on his own behavior.
A blind man inched his way along the busy street during the rush hour until he felt the curb with his foot. He paused until he sensed a person standing next to him, then he said: "May I accompany you across the street?" "Yes, certainly" came the reply from an elderly woman as she took his arm. The two persons walked safely across the street as cars and pedestrians whirled about them. When they came to the sidewalk on the other side of the street, the blind man turned to thank his escort, but before he could phrase his appreciation she said, "Thanks for the safe crossing. Being blind is made bearable because of people's kindness."
The real aim of criticism is not the destruction of cherished traditions - although a due regard for the facts does often compel us to revise older opinions - but a fuller appreciation of the beauty and truth of the creative work on which it fixes its regard. The word "criticism" is derived from the Greek word kritikos, which means "the ability to select or discriminate," hence, to decide or judge. The meaning of criticism is thus discriminating judgment.
