“… what is there in the subject of psychology to demand the attention of the manager?
Psychology, in the popular phrase, is " the study of the mind." It has for years been included in the training of all teachers, and has been one of the first steps for the student of philosophy; but it has not, usually, been included among the studies of the young scientific or engineering student, or of any students in other lines than Philosophy and Education. This, not because its value as a " culture subject " was not understood, but because the course of the average student is so crowded with technical preparation necessary to his life work, and because the practical value of psychology has not been recognized. It is well recognized that the teacher must understand the working of the mind in order best to impart his information in that way that will enable the student to grasp it most readily. It was not recognized that every man going out into the world needs all the knowledge that he can get as to the working of the human mind in order not only to give but to receive information with the least waste and expenditure of energy, nor was it recognized that in the industrial, as well as the academic world, almost every man is a teacher.”

Global Ideas from Pluto's Challenger (May 21, 2009)
Context: The best educators are the ones that inspire their students. That inspiration comes from a passion that teachers have for the subject they're teaching. Most commonly, that person spent their lives studying that subject, and they bring an infectious enthusiasm to the audience.I think many people have that enthusiasm, but they are prevented from being teachers because they didn't go through the teacher mill. Now you have teachers who have been through the teacher mill, yet they have no capacity to inspire anyone at all. It's the inspired student that continues to learn on their own. That's what separates the real achievers in the world from those who pedal along, finishing assignments.
