Intellectual 'work' is misnamed; it is a pleasure, a dissipation, and is its own highest reward. The poorest paid architect, engineer, general, author, sculptor, painter, lecturer, advocate, legislator, actor, preacher, singer, is constructively in heaven when he is at work; and as for the magician with the fiddle-bow in his hand, who sits in the midst of a great orchestra with the ebbing and flowing tides of divine sound washing over him - why, certainly he is at work, if you wish to call it that, but lord, it's a sarcasm just the same. The law of work does seem utterly unfair - but there it is, and nothing can change it: the higher the pay in enjoyment the worker gets out of it, the higher shall be his pay in cash also.
Mark Twain, A Connecticut Yankee in King Arthur's Court
