But when all is said and done, the fact remains that some teachers have a naturally inspiring presence and can make their exercises interesting, whilst others simply cannot. And psychology and general pedagogy here confess their failure, and hand things over to the deeper spring of human personality to conduct the task.
William JamesThe sovereign voluntary path to cheerfulness, if our spontaneous cheerfulness be lost, is to sit up cheerfully, to look round cheerfully, and to act and speak as if cheerfulness were already there. If such conduct does not make you soon feel cheerful, nothing else on that occasion can. So to feel brave, act as if we were brave, use all our will to that end, and a courage-fit will very likely replace the fit of fear.
William James
