Omg, Steffi, I know! I’m working on a book and it took a long time to stop editing while I write. After vomiting up the first draft, I actually printed out the whole mess and used colored markers to block out the stuff that goes together, and then went back into the doc to edit.
Write what you care deeply about. That’s what the word needs from you! The framing will come along in it’s own time. Just get the words out for now. :)
