Why????????

I have but one question for the universe at the moment. I'll write more later. My questions for this precise moment in time is this: Why is it so dang hard to write a book? More to the point, why am I so terrified of ruining it? I have so many ideas and I want to do a good job. Everybody says that you should just write out your first book and then throw it away, because IT WILL be crap. I don't want what I write to be crap! I'm under enormous pressure here to go against the tide of experts. In the words of Mork: heavy sigh.
