Once you outline (Don't let it becomes boring), start to fill in the spaces.
Write what is real to you--that is, get into the scene and describe what you see or feel as if you were right there. Writing is a lot like acting. In acting you have to be present to your character.
I find that when I don't like what I've written it's because I haven't even been close to the scene I am describing.
Easy? No. Not at all. Try it. You have to feel the place you are describing, smell it, see the details, hear the sounds.
So Rule #5 is: Be present in the scene you're describing. Like Alice, drop into the world you are describing.
