I remember one discussion over at the forum, where the topic was the usual question by non-writers "How do you get your ideas?"
And Diana's reply was something to the effect that a writer's problem mostly is not getting ideas, but stopping them from popping up all over the place.
My thoughts back then were "You'll never be a writer then. How could you be? You came up with this story idea with enough difficulty, and it's not even fully formed."
And tell you what? About a year later story ideas do come when least expected. Constantly. Sometimes they are only fleeting thoughts, and I forget them quickly. But sometimes the ideas stick and flesh out a bit, and won't leave me in peace, until I write at least the idea down.
I guess I'm a writer now. In spirit at any rate. :)
