There will always be more tough changes to make.  Always!  And yes, this growth can be painful.  Change can be painful.  But in the end, nothing is as painful as staying stuck somewhere you do not belong.  You’re not the same person you were a year ago, a month ago or a week ago.  You’re always growing.  Experiences don’t stop.  That’s life.  It takes a great deal of courage to admit that something needs to change, and a lot more courage, still, to accept responsibility for making the change happen.  But doing so is worth every bit of effort you can muster.
