What's a Change Agent?

I never heard this term until my coach called me a "change agent" a few years ago.  He said there are people that are uncomfortable with change and therefore end up in the same "state" for a very long time.  I'm the complete opposite.  I embrace change and look to make change happen when I feel its needed.  Being a change agent is really, really fulfilling especially if what you're changing is going to have significant impact. Consider something in your life that you need to change and become a change agent.  Determine what the new "end state" is going to be and the steps needed to get there.  And then, get busy!  Don't let anything stop you from achieving your goal.
