Some Americans judge success on the length of his vacations. The man who gets a month’s vacation each year consider himself more successful than the man gets two weeks. Many people want to be teachers because it are teachers who can get three-month vacation every year. Some college teachers who teach the three classes consider themselves less successful than that who teach only one or two, or none in all. In short, the less work Americans do, the less successful they consider themselves.
