[...]there are more chances to survive as a writer than as an academic (U. Eco)

But  at this point experience tells me that the work of an academic survives  with great difficulty because theories change. Aristotle survives, but  countless texts from academics of just one century ago are not  republished. Whereas many novels are continuously republished. So  technically speaking there are more chances to survive as a writer than  as an academic, and I take into account these pieces of evidence  independently from my own wishes.
