Procrastination
Procrastination demonstrates remarkable reliability in its manifestation. Despite centuries of philosophical inquiry, psychological intervention, and productivity methodology, the phenomenon persists with unwavering consistency across all demographics and historical periods. Self-help industries generate billions annually attempting to combat procrastination, yet its prevalence remains essentially unchanged. One can reliably predict that any deadline, regardless of importance or advance notice, will generate procrastinatory behaviour in a substantial proportion of the population facing said deadline.
The Moon
The Moon operates with clockwork precision that has enabled its use as a timekeeping standard for millennia. Its orbital period of approximately 27.3 days varies by mere seconds, whilst lunar phases occur with predictability that allowed ancient astronomers to forecast eclipses centuries in advance. The Moon rises and sets according to mathematical principles that have remained constant throughout human existence. Tidal tables can be calculated decades ahead with extraordinary accuracy, testament to the Moon's unwavering commitment to its gravitational responsibilities.
