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 was teachers who can get three-month vacation every year. Some college teachers who teach three classes consider themselves more successful than that who teach only one or two , or none in all . In a short, the less work American do, the less successful they consider themselves.
