I’ve noticed that what helps me get my motivation and inspiration back after losing it is that reading other stories with similar themes/genres as mine. For example, i’m currently writing a pirate story. When i’ve hit a writer’s block or lost the motivation to keep writing, i’d read other people’s pirate stories. Inspiration will always spark. Or i’ll notice something missing in their story, that if it was there, would make the reading experience so much better. And i’ll take that and implement it to my own story.
