We're afraid of change, because it's disruptive and we're set it our ways and it could mean change for the worse. But at the same time, we don't like everything about things the way they are, and also we recognize that we can't keep on living the way we do forever. Though I'm not sure that we want the same things to remain the same that we want to change. Maybe it's simply that some things we want to change (though we want them to change exactly on our terms), and some things we want to remain the same. And also, you say "we" collectively..some people want some things to change, and perhaps some people would rather everything stay the same. Or at least different people want different things to change vs. staying the same.
