For the past two days I've had great editing sessions. Tonight...not so much.
It's a strange thing to be a writer. One day you can read what you've written and feel like you're the next Tolkien or Bradbury. The next day you can read that same text again and wonder if you should delete the entire chapter and start fresh. I've learned that during these bad days, you just have to plug away at the editing and look forward to the next editing session, because more often than not everything will turn back to gold tomorrow. :-)
