The great source of literary enjoyment, which is the successful exercise of intellectual power, is, by such a mode of presenting a subject, cut off.

Secure, therefore, severe study.

Let the pupil see that you are aiming to secure it, and that the pleasure which you expect that they will receive is that of firmly and patiently encountering and overcoming difficulty; of penetrating, by steady and persevering effort, into regions from which the idle and the inefficient are debarred, and that it is your province to lead them forward, not to carry them.

They will soon understand this, and like it.
Never underrate the difficulties which your pupils will have to encounter, or try to persuade them that what you assign is _easy_.

Doing easy things is generally dull work, and it is especially discouraging and disheartening for a pupil to spend his strength in doing what is really difficult for him when his instructor, by calling his work easy, gives him no credit for what may have been severe and protracted labor.
If a thing is really hard for the pupil, his teacher ought to know it and admit it.
