"It is change, continuing change, inevitable change, that is the dominant factor of our society." -- Asimov
As a history teacher, I've trained myself to see the change in our society. I love to look back through history and see movements (people, ideas, things). It makes our everyday lives seem worthwhile somehow. We are all a part of the constant change happening to us, by us, around us. It's change that drives the species. We are the only ones that think about the past, the present, and the future. We are constantly evaluating our paths. Sometimes we stay on the current path and sometimes we deviant. But the point is we move. We are constantly in motion, changing the who we are are, what we want, what we do. We are change.
I'd like to think the changes are always positive. Of course that's not true, but the thought holds so much hope in it. To always be thinking of a better world, a change for the better. That's what we strive for...
