Thread: I want to write a book

I spent years constructing the world, the characters, ect. but when I put pen on paper I realize how little I know. It's the tiny little details that keep me from writing.

Most of the time when this happens it sets me into what I like to call a thinking episode. Should I just write it out with little planning? Or spend hours writing well placed paragraphs editing on the way(extremely time consuming)? I don't know which is more efficent in the end.
