Currently I am planning to do a short story or two featuring the back story of some of my main characters from Hell has its Demons. I am still doing quite a bit of background research for the novel, and this takes some time, and I keep feeling the urge to get some writing done. But I think the problem would be if I went off and wrote about other characters and setting I might start losing the focus on my main project. Also writing some shorts about the same characters might help flesh them out and be a good work out for getting the right style for the novel.
So if it worked for her, it can’t be such a bad idea! Although I am rather concerned that it took her ten years to do all her background research. Sometimes I feel that it might take me at least that long!
