The highest reward for a person's toil is not what they get for it, but what they become by it.
John Ruskin
My crown is in my heart, not on my head, Nor decked with diamonds and Indian stones, Nor to be seen: My crown is called content: A crown it is, that seldom kings enjoy.
William Shakespeare
Two men please God -- who serves Him with all his heart because he knows Him; who seeks Him with all his heart because he knows Him not.
