Don't let your writing be constricted by any kind of rules or boundaries; let go and allow your creativity to flow freely throughout your being. Writing is supposed to be about freedom of speech and letting your voice be heard. Go back to a time when you were innocent and carefree and all the petty problems of the world didn't mean a single thing. Take that feeling of absolute freedom and simply write; write and let your mind run wild in every way possible. Don't let a single bit of your creativity go to waste and just write.
