There are moments when the leading mind must have strength enough for two, but this must not last.

Its glory is to raise the mind of the learner to equality with itself, not to keep it in leading strings, but to make it grow so that, as the master has often been outstripped by the scholar, the efforts of the younger may even stimulate the achievements of the elder, and thus a noble friendship be formed in the pursuit of what is best.
Educators of youth are exposed to certain professional dangers, which lie very close to professional excellences of character.

There is the danger of remaining young for the sake of children, so that something of mature development will be lacking.

If there is not a stimulus from outside, and it is not supplied for by an inward determination to grow, the mental development may be arrested and contented-ness at a low level be mistaken for the limit of capacity.

A great many people are mentally lazy, and only too ready to believe that they can do no more.
Many teachers are yoked to an examination programme sufficiently loaded to call for a great deal of pressure along a low level, and they may easily mistake this harassing activity for real mental work, and either be indeed hindered, or consider themselves absolved from anything more.
