Gutta cavat lapidem, non vi sed saepe cadendo. (The drop excavates the stone, not with force but by falling often.)
Dripping water hollows out a stone
What is harder than stone? What more soft than water? Nevertheless hard though the rock be, it is hollowed by the wave.
Stones are hollowed out by the constant dropping of water.
"Gutta cavat lapidem." (Dripping water carves a stone.)
Either you pursue or push, O Sisyphus, the stone destined to keep rolling. [Lat., Aut petis aut urgues ruiturum, Sisyphe, saxum.]
