I don't believe in writer's block! I've learned that if I feel stuck, it means there's something in my manuscript that isn't working and I need to go back and fix it. My subconscious is holding me back.
Of course, inspiration doesn't strike every day. To coax it to emerge, I go for long daily walks with my rescue lab, Bella, Something about physical activity helps jump-start the mental process. And I always remind myself that it's my job to write, and that I'm incredibly lucky to have this job. So there isn't any room for the luxury of writer's block!
