E. Ce Miller of Bustle.com, while lamenting the fact that she did not complete her novel in thirty days, finds hope as she lists seven authors which took their sweet time:
"The first November after I finished graduate school, it seemed like everyone was completing their novels quickly but me. During that post-NaNoWriMo winter, one Facebook status after another declared that someone else had written a novel in 30 days; all but pointing a finger through the computer screen and directly at my face, shouting "neener-neener!" Now, I’m not generally one to begrudge another’s success, especially if we’re friends — and I really love to read, so if there weren’t people out there writing novels prolifically, then at some point I could be at risk of running out of material, which would be terrible. But still, all the cheerful statuses made me a little nervous. OK, a lot nervous. Nervous enough to throw in the literary towel completely and become something far less intimidating — like a bunny wrangler or a mime."
"It took author Audrey Niffenegger over four years to write The Time Traveler's Wife (and another seven to complete Her Fearful Symmetry.) The author herself admits to being a slow writer. Her reason? Because writing is fun. You gotta love that. Here's a lady who's written these two gorgeous novels — one a romance that transcends both time and space, and another about identical twins who uncover some devastatingly complicated family secrets — taking all the time she wants to do so, and totally owning it."
