Education should focus on practical usefulness and responsibility rather than intense application to impractical studies.

Original passage

It is not well to crowd the mind with studies that require intense application, but that are not brought into use in practical life. Such education will be a loss to the student. For these studies lessen his desire and inclination for the studies that would fit him for usefulness and enable him to fulfill his responsibilities. A practical training is worth far more than any amount of mere theorizing. It is not enough even to have knowledge. We must have ability to use the knowledge aright.
