One must imagine Sisyphus happy.
Camus wrote this in 1942, during the German occupation of France, when absurdity was not a philosophical exercise but a daily fact. He was watching people search for meaning in a world that kept refusing to provide it. The line is his answer to that refusal: not that the suffering disappears, but that the person pushing the rock can still own the act of pushing. It speaks to acceptance today because it separates happiness from outcome, and locates it in the choosing.
