Samuel Johnson, The Rambler
155 (September 10, 1751):
Indolence is therefore one of the vices from which those whom it once infects are seldom reformed. Every other species of luxury operates upon some appetite that is quickly satiated, and requires some concurrence of art or accident which every place will not supply; but the desire of ease acts equally at all hours, and the longer it is indulged is the more encreased. To do nothing is in every man's power; we can never want an opportunity of omitting duties.
