They are
I know I'm meant to enter only my own words here, but these words are too significant, and were phrased too well, for me to even attempt to match them: Writers will write because they can't not write. Repeat that over and over to yourself until you get it. Do you know someone like that? Someone who does what they do, not for money or glory or love or God or country, but simply because it's who they are and you can't imagine them being any other way? - Mark Pilgrim
I know very few people like this, but those I know are wondrous.
