It happens to everyone from time to time: You’re just not too excited about being a writer anymore.

As we all know, the road to writing “success” can be a long one. One that seems, at times, never ending. Because even if you reach your goal, whatever that may be, there’s a new goal waiting for you beyond that one. A new book. A new series, article, or essay. You have to finally admit it: you’re tired.

Is that a surprise? Most people who write have a small battalion of flying objects in the air: young children to raise or elderly parents to care for or a significant other or friends who require time and attention (and nights out)—in other words, a life. We’re constantly racing to meet a self-imposed deadline, upset that we “never have enough time.” Is it any surprise that we eventually reach a point of exhaustion?
