Writers have long employed "exertion" to evoke both the tangible strain of physical labor and the intangible burden of mental effort. In some works, the word underscores the concrete demands of bodily activity—whether it’s the overwhelming fatigue of battle or the physical toll of an arduous journey [1, 2]—while in others it hints at the inner struggles and commitment required in intellectual or emotional pursuits [3, 4]. At times, it even carries an ironic note, as characters remark on avoiding effort or lamenting the needless application of energy [5, 6, 7]. In this way, "exertion" becomes a versatile term that not only charts the progress of personal resolve and endurance but also reflects society’s varied attitudes toward action and inaction, thereby enriching the thematic landscape of literary works [8, 9].
