For me, revision is the most rewarding part of the writing process. It’s the time when all the false starts fall away, when the infelicities of language become fully functioning turns of phrase. When all the hard work of original composition has been completed (mostly), and I can turn my attention to issues of language and character.
And, because I’m old-fashioned when it comes to revisions, working with pen and paper, I can physically see the work improving. I can touch the improvements. Feel them. I do it this way because I’m practically incapable of carrying out successful, big-picture revisions purely on my laptop screen. I can’t see the sentences as they’re actually written, can’t see the story, if I can’t also touch it.
