“Any significant change can and probably will threaten the self-concept. Suppose the woman who defines herself as an efficient secretary is suddenly confronted by a new office situation so chaotic (or filled with new and confusing computer equipment, let us say) that she no longer can feel that she is operating at peak efficiency. In other words, some external change in her environment (the office situation) has put her out of kilter vis-à-vis her self-concept. In such a case, the woman who defines herself as an efficient secretary is going to be worse than unhappy; she is going to be profoundly shaken. If she is to be happy again, she will have to take some action. She may struggle to learn about computer systems to regain her old efficiency; she may quit her job and find a simpler one; she may try to convince the boss to go back to the old way of doing things in the office; she may elect some other course of action that will somehow get her self-concept back in tune with her everyday reality. You may be thinking that the simplest thing for our secretary to do would be change her self-concept to something like, “I’m an old-fashioned kind of office worker who doesn’t learn new tricks.” But it’s been psychologically proven that the self-concept is so deeply engrained, and so devoutly protected, that most people will go to almost any lengths to protect it as it stands today.”
