My background is in film.  I technically consider myself a filmmaker.  I became an author by chance.  Well, not really by chance.  I write because I have to.  It's kind of like going to the bathroom or being in love.  You can try to hold it as long as you want, but eventually you just have to let it out.  There's a certain joy that comes with that release.  I have found it is better to write and let it out.
