The great teachers are those who are able to elicit a pleasurable response toward the most rigorous pursuits, but the problem for the teacher is not only to make difficult work tasks pleasurable but also to develop a capacity for work. This constitutes a process of teaching for delayed rewards over an ever-increasing temporal span so that the student will strive through some misery to seek long-term goals. Patience, repetition, and arduous industry are still required for long-term achievement and happiness in almost every activity of life. Most adults will testify with pride to those endeavors that represented, for them, hard work and true discipline (Madsen & Madsen, 1998, p. 25).
