Writing Question:

Years back, I read an article or book on writing. I do not remember
the title or author, nor do I remember if it was part of a larger book
or in a writing magazine. It was about plotting, and where your story
really begins. There was a part that went (roughly paraphrased) "Your
story really begins when your main character is hit in the back of the
head by a brick." The whole point was that a story doesn't start
until something new intrudes upon the normal, orderly life of your
main character. As Emily Dickinson said:

"THE BRAIN within its groove
Runs evenly and true;
But let a splinter swerve,
'T were easier for you
To put the water back
When floods have slit the hills,
And scooped a turnpike for themselves,
And blotted out the mills!"

A story is what happens to a character when its life swerves from its
groove, and its brain is taken along for the ride. Or vice versa.

I very much like that way of thinking of stories. Unfortunately, I
don't remember much of the remaining advice from the article, that was
the part that stood out to me at the time I read it. I'd very much
like to read it again. Which brings me to my question:

Does this article sound familiar to anyone?
