Belief in oneself is incredibly infectious. It generates momentum, the collective force of which far outweighs any kernel of self-doubt that may creep in.
I find inspiration in many places. Sometimes music gives me the kernel of a story. Sometimes it's dissatisfaction with the plot of a movie or a book that gets me thinking. Sometimes it's love of a movie or book.
A standard sitcom... is a very standard idea, like these people falling in love and living with each other, and all these people living with each other. It's like, okay, we hooked them up in episode 15, how do we bust that, how do we find a new kernel in it?
Those of us with this ancient compulsion to tell stories sometimes start with a single kernel of something.
It's not even my job to educate, but what I do is try to facilitate by creating a book that works on different levels. I do want to entertain and bring some joy to the reading experience. If it holds a little kernel of knowledge that readers choose to explore, well, that's great.
