Gandalf
A wizard is never late, nor is he early. He arrives precisely when he means to. This philosophical stance on temporal reliability has become one of cinema's most quoted declarations, establishing Gandalf as the benchmark against which all punctuality is measured.
Throughout his tenure in Middle-earth, Gandalf consistently appeared at critical junctures, whether summoning eagles, breaking spells, or inspiring last stands. His reliability extends beyond mere timeliness to encompass unwavering moral constancy.
Procrastination
Procrastination's reliability operates on an inverse principle: one can consistently depend upon it to manifest whenever important tasks present themselves. In this regard, it demonstrates remarkable predictability, appearing unfailingly during tax season, before examinations, and preceding professional deadlines.
However, this reliability serves counterproductive ends. The phenomenon reliably ensures that work expands to fill available time, then overflows into stolen sleep hours and compromised quality.
