Most of them are ignored at one point or another. Sometimes to good effect, sometimes…meh.
I’ve been banging on this idea for a book on and off for the past several months. I put it aside and it resurfaces. I pound away at it for a while and then put it away again.
One of those rules I mentioned is that a writer should not fall in love with his words. Most of the time, this refers to not being reluctant to cut dialog, scenes and even whole chapters from a book if it really doesn’t work.
The same could probably be said for ideas. I’m enamored of this idea and I believe there is a story in there somewhere. Believing doesn’t mean it’s real and I’m right. After this much pounding, it actually suggests there isn’t a story there (or, perhaps, I’m not the one to tell it).
Still, I do like the idea and, contrary to a “rule” of writing, I’m going to continue to pound on it until I change that round hole into a square.
