In addition to carefully guarding my obligations, I’m incredibly conscientious about managing my time. Because my time is limited each day, I cannot afford to allow a large deadline to creep up on me, or a morning to be wasted on something trivial, because I didn’t take a moment to craft a smart plan. The Damoclean cap on the workday enforced by fixed-schedule productivity has a way of keeping my organization efforts sharp. Without this looming cutoff, I’d likely end up more lax in my habits.
