How can I stop feeling guilty about sleeping less than eight hours?

The eight-hour rule is useful, not absolute. Laozi would recognize this—we often force ourselves into rigid patterns that contradict what our bodies actually need. Some seasons of life demand less sleep. Some bodies run well on seven. The guilt usually matters more than the hour count itself. Instead of chasing a number, I'd suggest noticing: Do you feel rested when you wake? Can you think clearly through your day? Are you choosing less sleep, or is anxiety keeping you awake? That distinction changes everything. If you're truly sleeping what your body needs and functioning well, the guilt is just noise—old conditioning telling you you're doing it wrong. Try this: for one week, skip the calculation entirely. Just sleep until you naturally wake, and notice how you actually feel. No judgment, no comparison. Often we discover we need less than we thought, or that our real problem isn't hours—it's consistency, or what happens right before bed. The examined sleep is already better than the guilty one.
