In med-school, my professor used to say to be great at anything, it takes three steps.
I feel it is necessary to help people "see" the benefits of Dramatica by actually showing them successful examples they can relate to. Say, a fantasy writer could be referred to Tracy Hickman as a very successful example.
Then you encourage them to try the theory in its easiest form. Let's not talk about things like PSR's and so on. Just basic throughlines. Tailor a simple exercise for them( We can all come up with this in the forum). Let them actually feel like they can "do" it.
Then in the process we "teach" them. And probably leave them to "teach" other writers(Excitement is a powerful motivator).
One of the reasons I'm really digging deep into the theory is that I'm writing an Epic Fantasy book. When it's a global success, I'll tell everyone (By example) about one of my secret weapons. Dramatica.
Stay blessed guys.
