I was having a conversation today with a coworker who, after much thought, I eventually decided is an ISFp. Anyways, I was discussing with her about a novel I'm currently writing. Basically, my approach to things like this is to define the context before the content (in this case, deciding chapter titles and noting a summary of what's to happen, before actually writing the story itself). Anyways, after explaining to her I was about 1/3 of the way through designing the chapters, she said to me "How can you know what you're going to write in advance?" or something along those lines. Could this be an example of Ni vs. Si ways of thinking? Or am I completely along the wrong lines here?
