When writing, painting, or even packing boxes to move from one house to another, structure helps you know how to start, the path to follow, and where to end.
Here's the basics to the seven point system:
Plot Turn 1 - Call to adventure
Pinch 1 - Apply Pressure
Pinch 2 - Apply even more Pressure
Plot Turn 2 - Resolve to do something - The power is in you (your MC)
Here's the system put into action with HARRY POTTER.
Hook - sad little Harry under the stairs
Plot Turn 1 - finds out he's a wizard
Pinch - the scary Troll he and his friends battle
Midpoint - Harry sees the scary guy (I think it's voldemort) sucking on the Unicorn blood and he resolves to do something to get the bad guy
Pinch 2 - they go down the hole and his friends all get taken out by the traps (big chess for Hermoine and Ron- remember)
Plot Turn 2 - Harry is alone and he has the stone in his pocket. He realizes that the power is in him because he's pure and his mother's love is what saved him and allowed him to live so he knows that's how he'll destroy (for a bit) Voldemort.
Resolution - Harry succeeds.
So freakin cool!!! If you're interested in watching the series for yourself, here's the YOUTUBE link for the first one.
How do you write? Structure aka Plotter or Panster?
