Well, For me there are a number of ways. For example, today I listened to some instrumental music by Clint Mansell and that got my creative mind flowing. And I was able to stay that way for atleast two to three hours. Another motivator today was reading some poetry of mine and also others that were posted online.
I've been also looking for other ways to help with writing my novel and I think I found one. To put it down on a storyboard. I got most of it in an outline and in my head, but I think it will be helpful to lay it out on flashcards. That way I can visually organize it and move things around if need be. We'll see how it turns out but I'm staying positive through and through.
