Whenever I'm writing, I'm constantly plagued by this feeling that I'm not writing enough, or else I'm in a hurry to get to some other part of the story. What's helped me is to slow down, take my time to really enjoy every part that I'm writing, and remember that the chapter will be over when it's finished.
Same thing on the book itself. The book is done when you've finished telling the story. I've found that the more I write, the more likely I am to have a complex story with a well-defined beginning, middle, and end pop into my head all at once.
After that, I plot the whole thing out and start trying to fill in details to connect the pieces together. When I work on any given part of the outline, I keep reminding myself to write until its finished and don't rush it. What happens is that I get into a groove of how long my chapters are (and I tend to write shorter chapters) that I shoot for going forward.
