"Gutta cavat lapidem." (Dripping water carves a stone.)

Dripping water hollows out a stone

Gutta cavat lapidem, non vi sed saepe cadendo. (The drop excavates the stone, not with force but by falling often.)

Either you pursue or push, O Sisyphus, the stone destined to keep rolling. [Lat., Aut petis aut urgues ruiturum, Sisyphe, saxum.]
