I have too many ideas and I can't settle on which novel to write first ... any advice?

Well, wewe could try to combine a few of your ideas. However, if they are so completely unrelated that doing so would be impossible, wewe could do what I did. Start with your favourite. And when wewe get a writers block, start another. At the moment I am uandishi over 10 stories, and that's working pretty good for me!

Just write them all out how wewe think they should go, any part, it can be any part: start, middle, end, anything inbetween. If there's any wewe like (or in my case all of my roughly 14-15 idea's) then just continue them all on as wewe get ideas. Another way to do it is play all the idea's out in your head, place yourself in the main character's shoes, be them, it's surprisingly fun, as wewe meet new characters along the way. It's a way to test your imagination, and if wewe get ideas about how certain characters, write them down their name, age, bio, status in book.
