Leisure
Leisure has often been defined as a quality of experience or as free time. Free time is time spent away from business, work, job hunting, domestic chores, and education, as well as necessary activities such as eating and sleeping. From a research perspective, this approach has the advantages of being quantifiable and comparable over time and place.
Management
Management (or managing) is the administration of an organization, whether it is a business, a not-for-profit organization, or government body. Management includes the activities of setting the strategy of an organization and coordinating the efforts of its employees (or of volunteers) to accomplish its objectives through the application of available resources, such as financial, natural, technological, and human resources. The term "management" may also refer to those people who manage an organization.
Leisure
The superficiality of the American is the result of his hustling. It needs leisure to think things out; it needs leisure to mature. People in a hurry cannot think, cannot grow, nor can they decay. They are preserved in a state of perpetual puerility.
