Tip of the Week: You can never have a manuscript accepted by an agent or for publication if you fear the possibility of rejection.
Now, that little pearl of wisdom is neither new, nor particularly unique to me. However, that doesn't mean it isn't true or valid. Lots of people do not want to submit because they fear the response.
