Obviously the line between "work" and "writing" is at best subjective--for lots of people writing IS their work, and even limiting the scope of the definition to the idiosyncrasies of my own life, my paid work involves significant writing, too.
When I think of Writing with a capital W, though, it's material that I came up with of my own accord and not something with external guidelines (commissioned research) or an original text (translation). Maybe the term is "creative writing."
thoughts on writing full-time, money
@ljwrites yeah I do much better with academic writing than i do creative writing bc at least then I’ve got a structure & a defined set of limitations based on the source materials
Fiction just exhausts me immediately, people who do it full time are crazy impressive
