"A man must be master of his hours and days, not their servant"
About this Quote
As a writer associated with the early 20th century's faith in self-management and efficiency, Book is speaking from a culture newly obsessed with measurable productivity. Industrial time - shifts, timetables, factory discipline - had trained people to treat the clock as a boss. His line is a counterspell aimed at the emerging middle-class condition: being "free" while living like a subcontractor for your own calendar.
The subtext is less about squeezing more output from a day than about reclaiming agency. "Mastery" here isn't macho dominance; it's authorship. Decide what the day is for before the day decides what you're for. That framing matters because it shifts time management from a technocratic checklist to a moral stance: if you don't set priorities, someone else will, and your life will feel like an inbox.
The quote endures because it names a modern humiliation with surgical clarity: the sensation that the hours belong to everything except you.
