Quintilian Institutio Oratoria 12.11.18

[18] But it is ourselves that make the time for study short: for how little time we allot to it! Some hours are passed in the futile labour of ceremonial calls, others in idle chatter, others in staring at the shows of the theatre, and others again in feasting. To this add all the various forms of amusement, the insane attention devoted to the cultivation of the body, journeys abroad, visits to the country, anxious calculation of loss and gain, the allurements of lust, wine-bibbing and those remaining hours which are all too few to gratify our souls on fire with passion for every kind of pleasure.
