My Own Voice? Style?

So many agents and writing advisors urge us to write in our own voice. I haven't the foggiest idea what "my own voice" is. I don't consciously write in a particular "voice," I just write what I want to tell.

I have, however, figured out what my own "style" is. It came about when a writer friend of mine read something of mine with no name on it, buried in a pile of other somethings of others. She said she recognized my style immediately. That got me to thinking, because I also didn't have the foggiest what my own style was. After much thinking, I believe I have nailed down a definition of my particular style. It's heavy on dialogue, light on descriptions, and is broken into short pieces--much as a screenwriter would write, I assume.

Yes, it may sometimes leave the reader filling in the blanks, but I feel that's what a lot of really sharp writers do. Writers of genre mystery, anyway. Mainstream may be different.
