Wired for Story wasn’t as practical for me as Story Genius was (also by Lisa Cron), which wasn’t to say that it wasn’t helpful. Lisa Cron’s emphasis on focus and making sure everything that happens in whatever you’re writing is there to drive action, which in turn drives character development is incredibly helpful. If it doesn’t cause your character to develop as a person, it shouldn’t be in the story.
But really, I love how Lisa Cron’s books have finally helped me define readability. It’s not how well-written something is, it’s about how tightly crafted the story is, how the characters develop, and whether what is happening is necessary or a reaction against what happened in the previous scenes. It’s about how not-shaggy a book is.
I would recommend Story Genius over Wired for Story, but, honestly, both are useful.
