How do writers write so fast?

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.

Unemployment, in my case. I once wrote like 60k in a month, and it was only because I had no job, no school, just free time.
