Personally, I should introduce myself to the author, so he DOES know someone that wakes that early and still has a boring, 7-3 job.

It all comes down to personality type. Certain people have the “get up and start changing the world!” personality, and some people have the “why am I wake when the sun hasn’t risen yet…” personality. I’m somewhere in between, since I wake instantly but don’t feel any strong urge to do something major at that time of day.
