“When a job is undertaken from necessity, or from a grim sense of disagreeable duty, the worker is self-consciously aware of the toils and pains he undergoes...But when the job is a labor of love, the sacrifices will present themselves to the worker--strange as it may seem--in the guise of enjoyment. Moralists, looking on at this, will always judge that the former kind of sacrifice is more admirable than the later, because the moralist, whatever he may pretend, has far more respect for pride than for love...I do not mean that there is no nobility in doing unpleasant things from a sense of duty, but only that there is more nobility in doing them gladly out of sheer love of the job.”
