When you read your work aloud, the pro is definitely that it sounds like it’s so much longer than it actually is. It gives you a gist of how much work you actually put into it. The con, unfortunately is, though you get to ferret out all your grammatical and flow errors, you can’t understand what other people’s take on things is. You only know the characters and story in one way. The only way to understand if your characters are real or relatable is to take a leap and let others read your work. Scary, but necessary.
