Arrgh! It's like everyone I know is against me actually sitting down to write. So I'm 9000 words behind my goal. This in and of itself isn't too horrible, since the idea of 2000 words a day is supposed to be an attainable goal. One of the reasons I'm so frustrated right now, is because I know I can write 2000 words a day. Not doing so is creating a cognitive dissonance to my self-efficacy of writing a word count each day.
Now there are several things I can do at this point. I can justify that other people took me away from writing, or I can say that I was too busy with other things, and that I'll just have to work harder. But none of these things will allow me to accomplish my goals. Instead I have to explore a way to set up time and talk to my loved ones about my goals. Support and open communication are the keys to setting myself up to succeed after failing.
So while we have established that the story is about a paradigm shift that will occur from a brother knowing more about his sister's life, and experiencing a different life, the actual reasons that he dislikes his sister is because she has strengths that he does not (and vice versa). As a matter of fact, his sister is a representation of his shadow (Jungian Shadow). To explore this, part of the shift is to take part of what his sister does differently that he is weak at, and strengthen it. By the end of the story, he will not hate that aspect of his sister, and will understand it better because of how his paradigm has changed.
How exactly this is to occur is still being worked out and is probably on the level of a Freaky Friday or Parent Trap type scenario.
