WHY PEOPLE TAKE US WRONG ??
It's because something has hit a nerve if you frequently take things personally when they are not personal. You are transferring to other people your own uncertainties and insecurities. What you don't like about yourself, you assume other people don't like, too. They are likely to have doubts about your capacity to perform tasks that terrify you. You anticipate that they will reject what you yourself reject.
For instance, you might condemn yourself and assume that others will judge you if you feel insufficient because you are the only person in the room without a doctorate. A meeting was actually convened because something needed to be discussed and everyone was concentrating on solving the problem. At that time, nobody is concerned.
