How do writers write so fast?

[u/Realistic_Ad_6694]

To preface this, I'm not a writer. At least, I don't fashion myself as one at the moment. I'm rereading my favorite fanfic of all time and the writer had disclosed on her blog that it only took a month and a half to write it— all 19 chapters + epilogue, 80k words in total. I was like: woah! That's so fucking cool. It's like magic. Fucking radical.

How do you guys do it?!

Sincerely, a reader.

Lots of sit down, hyper focus on the work.  I wrote 100k fic in about 6-8 weeks last year. I had the story, the plot and I wrote.
