On the other hand, it seems that even though some people appear to be rich in material possessions, many of them seem to be miserable and consider themselves unsuccessful when judged by their own standards of success. Because not all ventures can be successful, one should not set unrealistic goals for achieving success, but if one has self-confidence it would be unfortunate to set one's goals at too low a level of achievement. A wise man once said to a young man who was experiencing frustration with his own professional success, "You do not have to set your goal to reach the moon in order to have success in traveling.
