Q. I'm stuck at the beginning. How do I push the story forward?
Well, you need a provocation which will push the hero out of the Ordinary World and then eventually another provocation which will push him into the New World.
For example, if you're writing a detective story, a murder would do it. And then clues to the murderer could lead you into his world (which would be the New World).
For example, if you're writing a love story, some machination could lead you out of the Ordinary World where you meet the romantic challenge and then another machination could lead you both into a new world or state, such as Five Year Engagement (2012) where Violet has to move to another city.
The Hero's Journey and Transformation through a New World/State is the template upon which the vast majority of successful stories and Hollywood blockbusters are based upon. Learn about this at http://www.clickok.co.uk/index4.html
