Writing a book is a labor, sometimes of love, other times of persistence, occasionally of obligation, rarely (one hopes) out of sheer sadism or masochism, depending on who exactly the writer wishes to punish. Regardless of motivation, it is work. And like most jobs, time off can be a necessity during the whole process. Sometimes it’s a holiday, and in some cases in can be an entire leave of absence for months or years until the desire to resume overcomes the reluctance to dive back into the thing that made you walk away altogether.
And sometimes, you just need to tell the book to shove it.
