Here are a few thoughts on keeping the well from running dry.
- Grab ideas from a totally different topic pool. If you love writing about animals as main characters, try switching it out to biography ideas about animal trainers. Pick a nonfiction topic if you most often write fiction and do the same if your ideas tend to be mostly nonfiction, then choose a crazy loony fiction topic.
- Planes, trains, and automobiles....biographies, histories, counting books, how to books, games, any topic with these vehicles that will grab the interest of male readers.
- Interested in weather? How about how to make a rain collection device, monitor and track the temperatures on graphs, what makes a tornado so devastating, and the list goes on. Find a twist on weather that hasn't been overdone and run with it.
- Cultural diversity is a big topic and has thousands of twists and turns that a story idea could develop from. Ancient history of a culture, folktales retold, holiday celebrations, being bullied because of ethnic background, fears, teen traditions including marriage choices, and again the list goes on.
