The next part, reading like a writer: this is the one that comes the most naturally. If you're a writer and decide to read a book that is popular and bestselling or even becoming a movie, isn't there at least one thing you laugh at within the pages of it? Something that you would change or add if it were your own story? I always assumed that that's how fan fiction started (or because the reader just didn't want to let go of the world they loved and knew).
So what do you do if you read like a writer? I seriously don't know. It's something I've been having troubles with for a while. You can't just email the author and tell them what they did wrong or what they should change. Though that would make some people feel better, it's rude and snobbish and you'd only do that if you were stuck up. It may be hard to hear, but the books you read aren't just your books and you aren't the only one that has chosen it to be your "personal favorite".
