“If you are not making the progress you want, it is not because of the reasons you have probably thought. It is not because you are a weakling, or lack discipline, or are an ‘old dog’ who can’t learn ‘new tricks,’ or any of the host of depreciative things you have thought about yourself. Rather, there is a part of you that wants to accomplish an important goal  and another part of you that is expending just as much energy working against that goal—but for a very good reason: you are (understandably) trying to take good care of yourself, to protect yourself from what feels like disaster—just the work of any immune system ”  ~ Robert Kegan and Lisa Lahey
