From what I’ve read, novels are written by both planners and pantsers (those that fly by the seat of their pants) and even some who have elements of both. And you won’t know which one you are until you find out — shrug —there’s no wrong way to write, I suppose.
I don’t have that much to share since this will be my first NaNoWriMo.
I do have some advice, advice I’m taking myself by the way, is to write the story you think will be the most fun to write. I feel it will be easier to go start to finish if you’re having fun.
