Monday
Monday arrives with the absolute certainty of astronomical phenomena. One can predict Monday's occurrence with perfect accuracy for millennia into the future—simply count seven days from any given Monday, and another shall appear. This clockwork reliability distinguishes Monday from virtually all other human experiences. Wars may end, empires may fall, technologies may transform society beyond recognition, yet Monday shall continue its weekly visitation. Financial markets structure their operations around Monday's guaranteed arrival. The predictability extends to human behaviour: coffee consumption peaks, email volumes surge, and collective productivity displays consistent patterns. Monday's very inevitability contributes to its psychological weight—unlike illness, accidents, or good fortune, Monday cannot be avoided, delayed, or negotiated with. It simply arrives, indifferent to human wishes.
Surfing
Surfing exists in a realm of magnificent unpredictability that drives its devotees to obsessive forecast-checking. Wave conditions depend upon distant storm systems, local wind patterns, tidal movements, and seafloor topography—variables that interact in complex, sometimes chaotic fashion. A spot that produced perfect waves yesterday may offer nothing but confused chop today. Surfers must develop intimate knowledge of their local breaks, understanding how different swell directions and tide states affect wave quality. The pursuit of good waves has driven humans to remote corners of the globe, chasing ephemeral conditions that may last hours or minutes. This unpredictability, paradoxically, contributes to surfing's appeal—the reward arrives unscheduled, making each quality session feel earned through patience and dedication rather than guaranteed by mere calendar position.
