Separate writing for yourself from writing for an audience. Writing is a means of recording information either for yourself or for someone else. Writing for yourself means making notes: recording ideas, things you've done or ideas you have. Nobody else needs to see your notes, so they just need to make sense to you. Writing for an audience is different. The purpose is not to "write and see what comes out", but to carefully communicate ideas you have already given due consideration. Too many people get lost in writing because they mix these two things up, writing thousands upon thousands of words as exploration, then trying to edit into a something that makes sense to a reader. This serves neither purpose well - the exploration is constrained
