All writers have their little favorite moments that illustrate what writing is like in their perspective. To me, the most representative moment I've ever seen comes from the brilliant BoJack Horseman, one of my favorite shows of all time, in the episode "INT. SUB."
Showrunner Flip McVicker huddles in his darkened office, having a meltdown. He has produced a script that reads nothing but the eponymous "INT. SUB", because he has writer's block and it was supposed to read "subway". Diane asks him why he didn't just finish writing "-way."
His response does more to capture what writing is like to me than anything else I've ever seen.

It really just encapsulates everything about it for me. All the weird shit you think and do when trying to pull a piece together, exquisitely satirized.
Like, why, Phoebe, did the last scene remaining to draft for Mrs. Frost get completed crying to yourself under a table in a classroom at Lesley? Because "writing is a process!"
Why does it say "blah blah blah he says something to reach out obliquely without reaching out here blah blah blah" where the character's dialogue should be? Because "writing is a process!"
And why do you need to look at lots of pictures of Chris Evans in order to edit your Adonis novel? Because fuck off, "Writing is a process!"
No matter the question, the answer is always the same, in an increasingly frantic tone. "WRITING IS A PROCESS!"
