I'm pretty optimistic here, but my countdown experiment worked and it might work again. So a little background - I began the process of writing a first draft of 'Open Water' by labelling my document Open Water 10. The next day I titled my work Open Water 9. The idea was that I would countdown to a finished first draft. Voila - today I will be viewing my Open Water 1 and declaring it finished.
FYI - finished in this case means the first draft. I will then move to another project and Open Water will be returned to at some unspecified time in the future, likely when I am doing revision work.
Once I have a name and a sketch of my new story I think I will try this countdown approach again. It might work twice!
