Snail asked in the previous comments: Don’t you take breaks between books to recharge battery?
Short answer: Yes.
Long answer: That depends.
Because here’s the thing—I actually love writing. When I stop writing—say, to take a break—I don’t feel right. I get itchy. I need words. I need to make words. I love reading, and I have a stack of books a mile high that I want to get to—and will, slowly (meanwhile, still stockpiling more and more)—but there’s a part of me that is always worried that if I stop for too long, I’ll forget how to do this gig. You may think that’s silly, but I don’t. Writing is a muscle. Writing is a state of mind, too—a combination of guts and imagination. You have to pull a confidence game sometimes to get things done—be a master con artist, with yourself as the target. Convincing your mind, again and again, that you can do this. You can write a book. One hundred thousand words of a story that will take people to another place—and in a good way.
It’s not easy. But when it is, those are magical moments. And I’m convinced the magic is always there, even if I don’t always feel it when I’m struggling to find the words.
So, I take breaks. I recharge my battery with books and travel, and friends. I don’t schedule that in. I just do it when I need it, when I feel like it. But the act of writing takes care of me, too, in other ways.
