To feel sacrifice consciously as self-sacrifice argues a failure in love. 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, and will say: “I have made such and such sacrifices for this.”
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 latter, 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. The Puritan thinks otherwise; he is inclined to say, “Of course, So-and-So works very hard and has given up a good deal for such-and-such a cause, but there’s no merit in that — he enjoys it.” The merit, of course, lies precisely in the enjoyment, and the nobility of So-and-So consists in the very fact that he is the kind of person to whom the doing of that piece of work is delightful.Dorothy Sayers, The Mind of the Maker, pp. 134 – 135
