A number of years ago I got a book called Revising Fiction. The book was about how to revise . . . well, fiction.
One of the author’s big points was that the revision process is very distinct from the writing process. (It had better be, or he’d have no reason to write his book.)
He therefore stressed to writers that they should not try to revise while they are writing. Write when you write; revise when you revise. Don’t mix the two or you’ll get into trouble.
And you will.
If you let your inner critic drive you to start editing what you’ve just written, you’ll fiddle with it forever. You’ll get bogged down–repeatedly–as you write, and you may never finish your manuscript.
Revision is incredibly important. It’s how you get all the bad stuff out of your writing. But it’s a separate process, and a very important one. This led the author to an interesting perspective: Why do writers write? Frequently, so they can have something to revise. That’s not true all the time (certainly, it’s not true of me when I’m writing an article or a special report on deadline), but at times in a writer’s experience–particularly in the beginning–it may well be true.
His overall point about keeping editing separate from writing is extremely important, however. When one writes, one frequently should get the words down as fast as one can, without worrying about how good they are. You can fix them later, but finishing that first draft is vitally important.
In my own writing, I try whenever possible to follow the advice, "Write in a fury!" Do whatever it takes to bang out that first draft. Fix it later.
One of the things that means is that I don’t stop to look up citations. If I stopped to look up every Bible verse I need to quote, or type in all the bibliographic info for a book I want to cite, it’d break the flow of my writing and I’d lose precious time by getting sidetracked to look stuff up. As a result, I don’t (when I can avoid it).
Instead, I drop unique strings into my writing at points I know I need to revisit. For example, if I know that I need to insert a Bible verse, I frequently will write "(xx)" for the citation. Then, after I’m done with the first draft and am in the revision stage, I’ll go back and do an electronic search for all the "xx"es and replace them with the missing citations.
If the needs of the manuscript are more complex and I need to mark different kinds of places to revisit in the revision process, I’ll use other unique strings. I don’t want a combination of letters that will likely appear in the text, though, so I’ll use something uncommon, like "jj" or "qq" or "xjxj." It’s then a snap to look these up electronically.
Using the word processor’s highlight feature also can help. I may put a yellow highlight on the whole first draft and then go through it, turning the yellow highlight off as I revise individual sections. (That way if I need to skip a section for some reason, it’ll still be yellow and thus obvious that I need to go back and finish fixing it.)
I understand that for some in the publishing industry, typing "00" has been an equivalent of my "xx." I don’t like that as much, though, because (a) "00" can look too much like "oo" or "OO" (making it hard if you’re visually scanning a secion) and (b) the zero keys require one to take one’s fingers off the letter-keys and hit the less-familiar number-keys. "xx" doesn’t require that.
So for me, any way, double-X marks the spot.
