I see too many prose writers who get hemmed in by cliches and what they perceive to be the formal requirements of the genre. Writing is first and foremost a personal creative expression. It doesn't have to conform to anyone's standards but your own.
Writing in prose can be an amazingly liberating experience when you can conjure characters and places and entire worlds from your own mind. You have a God like power as you build a narrative according to your own imagination. Don't restrict yourself. Dream as big as you can and express yourself in any way you feel.
