What's harder than editing? Editing a book you haven't looked at for six months! In one sense, fresh eyes are a godsend; in another sense, however, getting yourself back into a story - and into the minds/hearts of characters - you've been away from for so long is a difficult thing to do. As such, deadlines are essential. So, with that in mind, I've set myself a Christmas Day deadline! And if I don't meet it, I can hardly complain when Santa doesn't leave any presents under my tree :(
For me, self-imposed deadlines are an important factor in keeping my writing not only on track but always positive and always going forward. How do you keep your work going in the direction you want it go?
