Work consists of whatever a body is obliged to do. Play consists of whatever a body is not obliged to do.

The work that is really a man's own work is play and not work at all.

Work and play are words used to describe the same thing under differing conditions

When some men discharge an obligation you can hear the report for miles around

A good and wholesome thing is a little harmless fun in this world; it tones a body up and keeps him human and prevents him from souring.

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.
