Discipline
This collection includes all notes related to sleep discipline, which refers to individual or social efforts to instill specific habits meant to improve sleep hygiene and/or sleep efficiency.
Benjamin Franklin's Poor Richard's Almanack (1732-58) is an early example of sleep discipline in the self-help strain: "How much more than is necessary do we spend in sleep! forgetting that the sleeping fox catches no poultry, and that there will be sleeping enough in the grave, as Poor Richard says. If time be of all things the most precious, wasting time must be, as Poor Richard says, the greatest prodigality, since, as he elsewhere tells us, lost time is?" (42). The other texts featured here represent turn-of-the-century treatises on the subject of hygiene and efficiency.
