I know. Believe me...I know. Every time another season of The Voice starts, I post about it. That's because it relates so much to having the voice in writing. While watching the show's premiere, I heard a phrase I just loved. Adam said something along the lines of,
"Your voice is not like anyone else's."
Uniqueness. It's key. You could write another story about vampires but you'll never get it anywhere near a publisher unless it's completely different than every other blood sucking story. Make your story unique, make your voice stand out, and then make it happen. Never give up.
And never stop writing :)
