Post publish edit and update is an iterative process
When it comes to the basic Post Blog element in WordPress, you could have “paralysis through analysis”, a form of writers block that makes you fret over every sentence. It’s like MS worrying over DOS 1.0 instead of envisioning future improved versions. Keep it simple, make it work, then improve and add more content/functionality.
Some worry this can make a poor first impression
A bigger worry would be if each gem you produced took way too much time and effort to be an efficient use of time. With a second-look on the second day or whatever, it’s easier to make incremental changes and additions rather than have a Post failure to launch.
