“Intelligent living. As a matter of self-protection, to say nothing of the wisdom of living a joyous life, the teacher must look to the problem of keeping an adequate margin of good health. This is largely the problem of proper rest and recreation. It is such a simple truth to say that when one is tired and half sick most any sort of work becomes barren drudgery, and yet this explanation is rarely thought of by the teacher who retires in disgust after a long evening spent in the useless task of correcting papers.”
