I must move! What is it that we biological human organisms desire? To move!
What is my passion in life? To move. To move myself, to move weight, to move ideas, to move products, and to move people.
In fact, when I think about it, the reason I hated my 95 job so much is that it restricted my movement. Being stuck in a cubicle preventing me from being out and about, walking. In fact, what I love the most about living in the city is my ability to walk around freely. To me the worst existence is to be stuck at home all day, regardless of how huge or nice my house might be. Or similarly speaking, to be forced to be stuck at the office all day.
