Merlin, via 43 Folders Clips has a video of Eric Idle, on John Cleese’s Approach to Writing. Aside from John Cleese’s specificity, Idle talks about how he had trouble finding collaborators until he started working with John Dupre (I don’t know how his name is spelled).
Collaborating with other writers for natural language writing is difficult. I find pairing for code much easier, and even for code, I have trouble. No one can read my mind, I want to name variables something else. I want a different setup. There’s always something.
If you find some good collaborators, treasure your relationship with them.
