And if you remember the story about Sisyphus, Sisyphus was punished by the gods to push the same rock up a hill, and when he almost got to the end, the rock would roll over, and he would have to start again.
Se lembrades a historia de Sísifo, Sísifo fora castigado polos deuses  a empurrar unha roca costa arriba, e cando estivera a chegar  ao cume do outeiro, a roca rodaría para abaixo,  e tería que volver a comezar de novo.
