I have a daughter who, when younger, possessed no barrier between her emotional self and the outside world. Her emotional insides spilled out all over, and, especially when I was sleep-deprived and probably a little paranoid, this really threatened me. It was as if she were embodying and expressing the insecurities and freaked-outedness I never express, and which I've learned over the years to keep hidden.
When I write, the story is always uppermost in my mind, and I feel that everything must be sacrificed to it. All elegant passages, all the curious details, all the so-called beautiful writing - if they are not truly relevant to what I am trying to say, then they have to go.
