They want you to change. You can't change! Maybe you work too hard, or eat too much, or communicate too little. Whatever the issue, you tell them that's just the way you are.
Not so. Think about two things:
* First, it's not the way you are. It's the way you behave -- a learned way of doing things (you weren't born a work machine, for instance).
* Second, since behavior is learned, you are capable of learning new behavior.
OK, you say, but why should you change?
You might decide to change your behavior if:
* It's in your best interest to do so (overeating and overwork can do nasty things to your health, for instance).
