Someone who is a great editor of their own work probably has other problems.
I read everything of mine at least twice before I post it. And then I read it again, immediately after I post! Is it because Medium content in draft is different from published? Maybe. (That used to annoy me. Now it’s a feature. Because suddenly “I am home” becomes “I am am home” when the lines split differently.) But rest assured, when I read it again four months later, I will find a flaw.
