Last summer, a friend of mine who writes across genres asked me how my writing life was. I told him, Great! I'm writing every day and getting paid for it! Which is still true, and which I'm still extremely excited to be doing.
Then he asked me, but are you doing any real writing? I had to pause because I didn't actually know what he meant. You know, he said, creative writing (fiction, poetry, etc.)?
It never occurred to me to designate writing in this way.
