Don't watch the clock; do what it does. Keep going.
The real wisdom here isn't about ignoring time—it's about adopting the clock's indifference to circumstance. A clock doesn't pause when the hour feels difficult or speed up when the work feels tedious; it simply continues its rotation with perfect, stubborn constancy. That's the model Levenson offers: not blind hustle, but the kind of steady persistence that doesn't negotiate with your mood or your doubts. Consider the writer who produces three pages daily regardless of inspiration, or the person rebuilding after failure who shows up to the same gym, the same desk, the same difficult conversation—not because they feel unstoppable, but because stopping isn't part of the mechanism they've chosen to become.
