As every writer knows, or should know, is that every story has three acts. Act I - Setup: Exposition, Inciting Incident, Plot Point One Act II - Confrontation: Rising Action, Midpoint, Plot Point Two Act III - Resolution: Pre Climax, Climax, Denouement These acts are important to putting a story together and is necessary to introduce the reader to certain parts of the world. For example, Act 1 is the setup act where the author introduces the reader to the world, the threat (antagonist) and the first major plot point. In Harry Potter the first act in the Philosopher's Stone introduced Harry, and by proxy, the reader to both the muggle and magical worlds, the idea of Voldemort and the prejudice Harry would have to deal with and the mystery of the stone. The other two acts are just as important, if not more so. The second act (which should be the longest) focuses on the threat presented to the protagonist and how it affects them, as well as the steps they're taking to stop it. Which directly leads to the third and final act, Resolution. This act is the finale, the antagonist should be defeated in this act and any loose ends tied up (unless they're being left for a sequel), it is important that this act is done right so that the reader isn't left dissatisfied, they should always want more. There is so much more to this structure that I recommend you read up on, even if you're already knowledgeable on it. Always worth learning more eh? Might help you get that plot point you're missing. Question time: Did you know about the three act structure before reading this? When you, that's right you who's reading this, are planning out your story how long and filled do you tend to make your acts? For me I tend to make act one short, possibly ten chapters at most, before kicking into the main conflict. How filled do you tend to make your second act, is it just the main threat or do you have multiple sub plots?
