Nietzsche was definitely antiwork, and saw diligence as a scam. An excerpt from “To the teachers of unselfishness”.
One praises the diligent man though he injures his sight, or the originality and freshness of his spirit, by his diligence; the youth is honoured and regretted who has “worn himself out by work,” because one passes the judgment that “for society as a whole the loss of the best individual is only a small sacrifice! A pity that this sacrifice should be necessary! A much greater pity it is true, if the individual should think differently, and regard his preservation and development as more important than his work in the service of society!”
Snip…
How often do I see that blindly furious diligence does indeed create riches and honours, but at the same time deprives the organs of the refinement by virtue of which alone an enjoyment of riches and honours is possible; so that really the main expedient for combating tedium and passion, simultaneously blunts the senses and makes the spirit refractory towards new stimuli! (The busiest of all ages – our age – does not know how to make anything out of its great diligence and wealth, except always more and more wealth, and more and more diligence; there is even more genius needed for laying out wealth than for acquiring it! Well, we shall have our “grandchildren”!)
Definitely worth reading the whole thing, at the link. Nietzsche can be dense but very rewarding to study if you’re… diligent enough.
