"Students rarely disappoint teachers who assure them in advance that they are doomed to failure"

This quote by Sidney Hook recommends that when instructors have low expectations of their students, the students will typically measure up to those expectations. It implies that if teachers believe their trainees and think in their potential, the students will be most likely to succeed. This is due to the fact that when students are given the guarantee that they can be successful, they are most likely to put in the effort and work hard to achieve their objectives. On the other hand, when trainees are informed that they are destined stop working, they may end up being prevented and quit prior to they even attempt. This quote motivates teachers to have faith in their trainees and to provide them with the support and motivation they need to reach their complete capacity.
