chatty") and ask him what countries he hasn't been to.

So, I assume, what he really means is he doesn't do
exercise. You won't find him at a gym or the track, let alone sharing
field with a slew of teammates. He says it doesn't make any sense to
hike in the area they live, which is San Francisco. "You go up, come
down, see a hundred other people on the trail, get into your car and
home. Why would I want to do that? Now hiking in the Gobi Desert,
would be fun."
It's in that same strain that he opted for self-employment. Though
has contracted with the same company, Learning in Motion, for the
four of eight years, at least he is not in an office atmosphere with
monitoring his comings and goings. It's not that he's not sociable,
just independent. Maybe, growing up on the Isle of Wight, he
got infused with the spirit of Jimi Hendrix, who he says gave his last
performance there, and John Lennon, who vacationed there with Yoko Ono.
They too were free spirits, sound in their sense of self as an
a greater and diverse world. It's the mindset of a guy that goes to
career service office of his college to consider his future and browse
through a few brochures of companies offering positions in programming

he realized there weren't too many people crossing nature's oven in the

barriers only made the destination more alluring, and he spent the better

expected when traveling to any country run on corruption, they were
to do a lot of improvising. It was an adventure fit to fulfill even a
diehard like Green.
At first it seems paradoxical that someone with this kind of energy
also be so satisfied by such a sitting-still activity as software development.
to think that the challenges inherent in travel are solely of a
nature is to overlook its true value. Every new culture stretches ones

MacroMind and previously at the BBC showed me that even in a larger
environment the territorial and property-based mindset affected even
teams within a company, sometimes engendering anti-productive

over and over."
I guess age really is a state of mind because, if one uses their

individuals that came before him, be they programmers or poets, Green
