Two from GKC
A MAN must love a thing very much if he not only practises it without any hope of fame or money, but even practises it without any hope of doing it well. Such a man must love the toils of the work more than any other man can love the rewards of it.
AMONG all the strange things that men have forgotten, the most universal and catastrophic lapse of memory is that by which they have forgotten that they are living on a star.
