As an academic (CS), I'm able to write one or two decent papers a year, in a very good year, three.

Looking at colleagues who write ten a year I already get existential angst, and have to actively tell myself that life is not a competition and some things are more important.

Writing fifty (while also teaching, writing grants, mentoring students, etc.) seems mind-numbing, even just in terms of the relatively routine tasks of formatting or proofreading papers, aligning figures, corresponding with reviewers, editors, co-authors, etc.
