I hear that 5 o'clock whistle in my mind like Fred Flintstone and I have to stop. I'm also not much of a morning writer. I have a sweet spot from about 11am to 4pm. But I really work during that time.
The term 'geek' for me is like you having a passion interest in something that is unabashed and you don't care if people think it's not cool. You think it's cool and that's your thing.
