No doubt about it, reworking a page is not like creating one.
Although the same amount of “work” might go into the revising as the forging the new, the process is different.
However, both have similarities. A weekly (or monthly) goal must be used to keep the forward momentum. (A goal is a dream with a deadline).
Careful plot and consistencies, from a character’s physical attributes and limitations to the time frame of the piece must be adhered to. Daily writing at the same place and same time must take place. Returning to the first 30 pages must be avoided in order to keep moving through the piece.
But the question remains, is rewriting two pages the same as creating two? Absolutely not. Yet in the rewrite, pages will disappear and new ones show up.
The 3by3 Writing Method does not address the speed of a writer, only that the constant, daily progress be made.
An 80,000 word book could shrink and expand during versions but there will always be a gold word count and there will always be a steady march to the end.
Answer, ultimately no/yes. Rewriting two pages requires a different skill set, but the same discipline as when working through the first draft.
One major difference is that the rewriting of EACH VERSION should take less and less time as the story theme, characters and conflicts come into focus.
If you rip the entire story apart, then it probably isn’t a rewrite… it’s most likely a new book with the same title.
