The beginning. I usually have no clue where to actually start a story or where the best place to jump into my characters lives. I have tons of chapters sitting in my folder that aren't necessarily beginnings, but random chapters of stories that I don't know how to start! There's one story I have eight chapters of, but I'm blocked on how to actually start it, lol. And now it's kind of dead in the water anyways because I started a collab with a friend that's really similar.
