Fear of deadlines helps a lot! If I get stuck, I take a walk, go do something else for a short time, do some Yoga, or pet the dogs. Most of the time if I'm really stuck, I go talk out the problem with my husband (who is co-authoring the steampunk book with me and plays a big role behind the scenes). That usually does the trick! Other things that help are researching something (which leads me to some other cool thing that gives me ideas) and watching The History Channel!
