[mtct]

Physical labor is great because you don't have time to worry about anything else.

Vous devez avoir, dit Candide au Turc, une vaste et magnifique terre? — Je n’ai que vingt arpents, répondit le Turc; je les cultive avec mes enfants; le travail éloigne de nous trois grands maux: l’ennui, le vice, et le besoin.

[ajlburke]

For those who don't know French (approximate):

Candide asked the Turk, "Do you have a vast and magnificent estate?" "I only have twenty acres," the Turk replied. "I cultivate them with my children; The work wards off three great evils: boredom, vice, and want."

- From Voltaire's "Candide" - one of the more fun (and short!) 'Great Books'.
