Finding your own voice is very difficult for a writer. Learning to say what you mean, to put words together so they make sense is challenging. Then, when you think you've done it...along comes someone with an opinion.
And they may say that what you said was dumb, or ill-expressed, or wrong.
It can be discouraging, that certainty some people have that you aren't doing things right.
Just remember, its your voice, your story, your call.
I have to remember this.
