Sisyphus is THE archetype of a person engaged in an ennobling struggle. Camus was the main culprit behind the dumb argument that Sisyphus had a meaningful life, rolling that rock repeatedly up the hill, only to have it roll down again. Today, you see people engaged in any sort of struggle with symptoms of pointlessness making similar arguments. There is a whole painful genre of entrepreneurial motivational commentary based on fetishizing the pain, blood and sweat of certain kinds of struggle into something sacred and noble. This is smarmy bullshit. You should not avoid hard work where it is the only path, but you SHOULD use every available trick and hack to mitigate the need for Sisyphean efforts.
