Sisyphean task

A Sisyphean task refers to a seemingly endless and futile effort, where one must repeatedly perform a demanding or pointless activity without achieving lasting success. It originates from Greek mythology, where Sisyphus was condemned to roll a heavy boulder uphill only for it to roll back down each time he neared the top. In modern usage, it describes endeavors that are laborious and never truly complete, often highlighting frustration or the sense of futility involved in persistent, unfulfilling work.
