To serve man, or even to serve myself
We certainly do not honour God when we bury or when we neglect to improve as far as we may, whatsoever talent he may have bestowed on us, whether it be little or much. In natural things as well as in spiritual it is a never-failing truth, that to him who hath, that is to him who occupies what he hath diligently and so as to increase it - more shall be given. Set me down therefore my Dear, for an industrious Rhymer so long as I shall have the ability, for in this only way it is possible for me, so far as I can see, either to honour God, or to serve man, or even to serve myself.
~ Letter from William Cowper to Lady Hesketh, 15th May 1786
