Are you writing a novel? I am.
Writing a novel requires the creation of a living, breathing alternative world. That’s hard work.
It takes years to write a book, between one and ten years. Annie Dillard says, “Less is so rare as to be statistically insignificant.”
When it bothers you that it’s taking you a long time to finish your manuscript, don’t give up. Keep going. Keep writing. Keep revising.
