Lesser-known steps of the writing process:
Finding all the paragraphs where you used some hyper-specific word more than once
Rearranging paragraphs that you swear you wrote in the right order but turned out to be totally backwards
Going for a walk, coming up with the perfect line, and forgetting it as soon as you get home and open your laptop
Creating a separate document where you can dump all of those nice sentences that no longer fit in anywhere
Waking up in a cold sweat because so-and-so was supposed to be barefoot but never actually took his shoes off
OP if I made add:
Realizing one crucial scene changes your timeline so you have to go back and shift everything slightly
Having long dialog between three or more characters and forgetting to mention who says what
Coming up with the perfect sentence while on a walk pausing to write it down, only to get home and realize you still have 5 more chapters to write before you get to that scene
