When I was in high school, I went to the Rueben Daniels Center of the Arts and Sciences. In my dance class we learned about theme and variation. What we had to do was choreograph a dance routine that was about one minute in length. Once we had our routine down, we had to choreograph two more dance routines based on the first one. More precisely, they had to be variations of the first by modifying it somehow without changing it completely. With writing this can also be done. Create a scene. Then, create two more scenes by varying the first scene. But, don’t vary things too drastically. It needs to be clear that your varied scenes are essentially the first scene but with slight differences.
What does this do? It works at developing creativity. It’s like a brain workout except its “bench pressing” words instead. So…have fun with it and think outside the box.
