There are no Rules. There are only techniques that work, or don't work.
Sometimes they don't work because they are the wrong technique. Try something else; save that technique for another time.
Sometimes they don't work because you don't have the chops to pull them off yet. Try anyway.
You don't learn things you don't attempt. So go ahead and try: writing is not a performance art: if you break it, you can always go back and start over.
