Writing 50,000 words of fiction really doesn’t take that much time. Slow writers find they can write about 800 words of novel per hour; a speedy writer (and good typist) can easily do twice that. Which means that the whole novel, from start to finish, will take and average writer about 55 hours to write.
If you had the luxury of writing eight hours a day, seven days a week, you could begin on a Monday morning and be wrapping up your epilogue in time for brunch on Sunday.
The truth is, though, that few of us have the luxury of writing eight hours a day, seven days a week. In fact, between school, jobs, and the host of other daily events that fill our lives, carving 55 hours of quiet time, however small that number looks on paper, ends up being quite a challenge.
