I've been planning to write a novel in my head for a while now. I've started about six others, but I've never managed to finish them - I get bored of writing them or I'm just not in the right mindset to finish them. But finially I've thought of an idea that I really like, I have a pretty good idea of how it will end, the characters are set - I'm ready to write it. I just can't figure out how to start it and everytime I think about it, I picture it more as movie than a book. I don't want to write a screen play... Does anyone have any tips or suggestions to get out of this mind set?
