In story, unlike life, you can always go back and fix it. You can set up what may seem absurd and make it rational. Reasoning is secondary to postcreativity. Primary and preconditional to everything else is imagination–the willingness to think any crazy idea, to let images that may or may not make sense find their way to you. Nine out of ten will be useless. Yet one illogical idea may put butterflies in your belly, a flutter that’s telling you something wonderful is hidden in this mad notion. In an intuitive flash you’ll see the connection and realize you can go back and make it make sense.
– Robert McKee, in Story
