A lot of people worldbuild when they daydream and have the bones of a story kicking around in their brain, but have to pay the bills and raise the kids etc so they never flesh it out and write it down. What’s your story’s premise? Fantasy, sci-fi, alternate history, mystery, western, whatever genre.
I’d love to write a really good acid western. So far all I have are daydreams about being a badass old west drifter to the music of Spindrift.
Edit: I suppose there’s also what I started when I tried (and failed) NaNoWriMo, which was a horror story about a pathogen that made people deranged killers of a spectacular nature. There was a fight in a stained glass factory, that was kinda cool. Should see if the laptop with the draft still boots…
(If I recall the movie correctly, it was basically The Crazies, but more violent and written before the 2010 version came out [never saw the 1973 version])
