"Bounding out of bed after an unbroken sleep, singing or whistling as he dresses, coming down with beaming face ready to laugh on the smallest provocation, the healthy man of high powers, conscious of past successes and, by his energy, quickness, resource, made confident of the future, enters on the day's business not with repugnance but with gladness; and from hour to hour experiencing satisfactions from work effectually done, comes home with an abundant surplus of energy remaining for hours of relaxation. Far otherwise is it with one who is enfeebled by great neglect of self. Already deficient, his energies are made more deficient by constant endeavours to execute tasks that prove beyond his strength, and by the resulting discouragement. Hours of leisure which, rightly passed, bring pleasures that raise the tide of life and renew the powers of work, cannot be utilized: there is not vigour enough for enjoyments involving action, and lack of spirits prevents passive enjoyments from being entered upon with zest. In brief, life becomes a burden. Now if, as must be admitted, in a community composed of individuals like the first the happiness will be relatively great, while in one composed of individuals like the last there will be relatively little happiness, or rather much misery; it must be admitted that conduct causing the one result is good and conduct causing the other is bad. "He who carries self-regard far enough to keep himself in good health and high spirits, in the first place thereby becomes an immediate source of happiness to those around, and in the second place maintains the ability to increase their happiness by altruistic actions. But one whose bodily vigour and mental health are undermined by self-sacrifice carried too far, in the first place becomes to those around a cause of depression, and in the second place renders himself incapable, or less capable, of actively furthering their welfare. "Full of vivacity, the one is ever welcome. For his wife he has smiles and jocose speeches; for his children stores of fun and play; for his friends pleasant talk interspersed with the sallies of wit that come from buoyancy. Contrariwise, the other is shunned. The irritability resulting now from ailments, now from failures caused by feebleness, his family has daily to bear. Lacking adequate energy for joining in them, he has at best but a tepid interest in the amusements of his children; and he is called a wet blanket by his friends. Little account as our ethical reasonings take note of it, yet is the fact obvious that since happiness and misery are infectious, such regard for self as conduces to health and high spirits is a benefaction to others, and such disregard of self as brings on suffering, bodily or mental, is a malefaction to others.
