I think in saying that I'm a martial artist, a writer trying to become an author, and a pianist, with a combination degree in business-marketing and mechanical engineering, that should pretty well show you I'm "just a little bit" diverse.
My ultimate goal is to see my life's work through in every facet of the creative process. It is currently in novel form. I would like to finish it, write the script, produce the movie, write the score, and even have an appearance on-screen in the film. I basically want ultimate and total creative control over the project, and think I might have enough talent to do it, even though it's not feasible to try to do it (insert "hours in a day" argument here).
I've written quite a few pieces for the piano, none of which I consider to be good. I'm working on finishing the bones of a piano concerto, of which the third movement is damned hard...I know I can't play it (yet). And I have a C-sharp minor fantasy of which I'm pretty proud, though I know it doesn't "change" enough for some people's tastes.
I've written and published four poems, though I have thousands of others stacked in notebooks around my apartment. I've written thirty or forty short stories, three of which are published, and many more are in forums around the internet, particularly Harry Potter forums because I like writing for kids every once in a while (though you'd be surprised the amount of adult feedback I get on those stories...

). And I have seventeen novels sitting on my computer in various states from "complete and editing" to "well, I wrote down the title, anyway". :p
So, that's a little about me. And I actually have to stress "a little".
