If you follow my Twitter, I recently bemoaned the fact that I realized I needed to change my entire novel to first person POV.
I was dreading the work. It was enough brain-numbing work to sit down and just edit my old chapters for consistency, plot, character, big picture questions, etc. etc. Now I would have to go through and recheck/change every single pronoun and verb TOO?!
Needless to say, I was doing my writer whining. I tried the "Find and Replace" feature (word to the wise, it doesn't work). I tried just skimming and changing each pronoun and verb. That didn't work either. I would miss ones and some sentences would just not sound right.
