looking back
If it takes two or three months to write a novel, I seldom have to look back at all. If it takes six month or more, and if I'm working on a bunch of other projects at the same time, I need to look back once or twice to get my bearings.
But I generally remember what I write well enough to make looking back unnecessary unless a lot of time, or a lot of other projects, get in the way.
I don't really worry about characters growth, or about characters changing into other people. I never have liked either of these terms. Both, I think, cause all sorts of confusion and story problems. I simply think of action and reaction.
Good characters change according to the events in their lives. This is true. But real people do not constantly grow. Neither should characters. Change can be for the good, or change can be for the bad, and whoever came up with the phrase "character should grow" needs to be horsewhipped.
I especially hate this advice because it's ruined some extremely good characters, particularly in series. As a reader, I find a character I love, and just then the writer makes him "grow," which often means I just lost the reasons I had for loving him.
If your wife gets raped and murdered, if your only child dies of cancer, you are going to change. But you may or may not grow.
And what's wrong with changing into a different person? That's what change is. The mild-mannered, soft-spoken, wimp of the week may become a completely different person after his wife is raped and murdered. He probably should.
I think a writer needs to do three things where change and growth are concerned. If you want a character to change or grow, then:
1. Give the character something that the average reader can see needs changed, or an area where the average reader can clearly say, "He really needs to grow out of that." It's amazing how often writers forget to do this.
2. Have something happen that makes the change or the growth necesaary. Writers forget this about as often as not.
3. Have the character decide to make the change, decide that the change is necessary.
And two other things a writer should remember.
1. It sometimes works even better to have the character reject the change. Or even to change for the worse.
2. If a character is going to change for the better, he often needs to change for the worst before this happen. The meek, mild-mannered man with the murdered wife may, probably will, first change for the worst because his world is upside down, and the only thing on his mind may be murder, torture, revenge, hate, etc.
It's then the act of murder, torture, revenge, and hate that changes him for the better in the end.
