Contrary to what some may think, I'm pretty indifferent to change. It depends on what the change is that determines how I respond to it. Generally, I like change more than keeping things the same, because changing something renews my interest in it and I find it to be pretty exciting, but big things are things that make me very uncomfortable, like moving, entering a different stage in your life (like graduating high school and moving away to college, or graduating college and entering the work field), or other things like that.
You wouldn't read a book or watch a TV show where the same thing keeps happening, would you? I guess that's the frame of mind that I have regarding change. Even though those things make me uncomfortable, it changes things up and makes things more interesting and less stagnant and stale, and I think that's important in life.
As far as PC is concerned, I'll almost always prefer change to keeping things the same, and I don't really understand the "If it isn't broken, don't fit it." mind frame some people tend to have. It's also something that generally frustrates me more than anything else here. That being said, I do understand that some people are uncomfortable with change, but that still doesn't really hold back the thought that those people are generally holding things back.
