"Be yourself. Above all, let who you are, what you are, what you believe, shine through every sentence you write, every piece you finish." -John Jakes
I don't know about every sentence you write. But at the very least, the important ones. The plot-building ones. And the humorous ones. And the intense ones. And the ones at the beginning. And the ones that will make the reader pause, and then hurry on. The painful ones. The exultant ones. The ones full of tension. The ones that promise. And the ones at the end. And the middle. Those sentences. You get the idea.
In film, a character is what the actor brings to the part, and a good actor will have us remember the character and the character's story.
But then look for the actor again in another film.
So shine through, but be invisible.
Easy peasy. Right?
