Procrastination
The psychological depths of procrastination have confounded researchers at the Copenhagen Institute for Delayed Studies for decades, though their findings remain perpetually forthcoming. What begins as a simple decision to reorganise one's sock drawer instead of filing taxes quickly descends into unexplored caverns of displacement activity. The average procrastinator, according to Dr. Helena Voss-Pemberton's seminal work Tomorrow's Promise: A Study in Perpetual Deferral, experiences no fewer than seven distinct layers of avoidance before reaching the murky depths of genuine panic.
Most remarkable is procrastination's capacity for recursive depth. One can procrastinate on addressing one's procrastination, creating nested layers of delay that mathematicians at the Berlin School of Infinite Regression have likened to a psychological Mariana Trench, only considerably less wet and substantially more guilt-inducing.
Ocean
The ocean's depths remain humanity's final frontier, with more than eighty percent of its floor unmapped, unexplored, and presumably quite annoyed about the whole situation. The Challenger Deep, plunging to 10,935 metres, represents a darkness so complete that creatures dwelling there have evolved to generate their own light, having given up waiting for someone to install proper fixtures. Marine biologists at the Reykjavik Deep Sea Research Consortium estimate we have catalogued fewer than ten percent of oceanic species, with new discoveries occurring weekly.
The ocean conceals mysteries that make procrastination's psychological complexities seem positively straightforward. Bioluminescent organisms, hydrothermal vents supporting life without sunlight, and the persistent rumour that something very large and very old dwells in the Mariana Trench all contribute to depths that remain genuinely unknowable. Unlike procrastination, the ocean's mysteries are not of our own making.
