Patrick Rhone on "what the world tells us": You Can't.
While his article isn't about change, you can perfectly read into it that way. Even if it's not verbally, you'll feel that sometimes you just fell like you can't change.
Well, here's Patrick's perfect answer:
"The world is wrong. You really can be anything you want to be if you put your mind to it. Those that do so, those that dare to dream and who refuse believe in limitations always figure out a way. The kid who rejects such notions becomes the adult who shows it all to be a lie. And, for every “can’t”, I’m betting there is at least one example of someone who proves the “can too”.
