I write with voice... no really!
So many writers have no voice.
Without it you feel as though you are reading a college research paper.
Who wants to read that? holding someone's attention in this fast paced, media rich, high stress world is difficult enough! Don't put them to sleep!
Now depending on what you need, the voice can change from funny to informative or anywhere in between.
I figure its kinda like acting...
... on paper.
