LIFEWORK — [Noun] The principal occupation or achievement that constitutes the main endeavor of a person's life. From the English words life (the condition that distinguishes animals and plants from inorganic matter) and work (activity involving mental or physical effort done to achieve a purpose). Unlike oeuvre, which catalogs a lifetime's output as a curated externality, or vocation, which implies a calling one might still abandon, lifework is the tangible, totalizing edifice built from the days of a lifetime. It is the scholar's definitive manuscript revised until the hand trembles, the farmer's hands permanently etched with soil from a single perfected acre, the activist's biography measured in incremental legal reforms—a mortal attempt to make a finite span cohere into a lasting shape, the final argument whispered back at entropy.
