The thing about writing, in general, is that you either are telling the truth and start from the beginning, or you know how it ends and have to find a way to get there. Take TV show writing, for example: an actor doesn't renew a contract, and now you have your plot point - their character must be written off the show. How you get there is wide open, and depends usually on how likely the show producers are to bring that actor back in the future.
When I write, I generally pepper things with liberal amounts of truth, but I almost never know where things are going to end up when I start. Sometimes this leads me to trail off in the middle, wishing I knew what was going to happen in the story I am telling, but not really able to get there.
This is more truth, I suppose, than fiction is. The best laid plans of both mice and men always go awry, we can't control our own destiny any more than we can control other people, all we can do is to keep steering the car back to the middle of the lane when it starts to drift, which we can only do if we're planted firmly behind the wheel of our own vehicle of destiny.
So never let anyone else drive your car while you are in it.
And remember: that's the way it goes, but it goes the other way sometimes, too...
