Ideas are the raw materials writers use to form stories and narratives. They are the fuel from which creative magic is made. But where do ideas come from, and what can you do when they dry up?
In my experience, ideas come to us when we are looking for them and willing to act on them. The world is FILLED with ideas. All we need to do is open our eyes.
When our stream of ideas dries up, it may be that we simply aren't getting enough input. The solution to this problem is both simple and enjoyable: start exploring the world. Read, go to the movies, take a vacation, take a walk, learn about a subject you know nothing about, meet new people, go to a concert, color, play with clay, draw with sidewalk chalk, pet a cat, get outdoors, people watch, cook a new dish.
If we're getting plenty of input but the ideas still aren't coming, the problem may be with us. We may be tired or burned out or afraid. To address these issues, take a break, relax a bit and do something different for a while. Then come back and start generating fresh ideas.
One great way to kick start your writing idea engine is to browse a pre-made book cover site, picturing the kind of story you'd expect to see between the pages. You may find that a particular book cover gets you excited enough to start writing again. If so, buy it and get to work.
