this terrible shock

To become acquainted with oneself is a terrible shock. ~ Carl Jung

ourself in disguise

We meet ourselves time and again in a thousand disguises on the path of life. -Carl Jung

So true, and sometimes we may even view ourself in disguise as the outsider or even the enemy! :)

accept to change

We cannot change anything until we accept it. Condemnation does not liberate, it oppresses.
- Carl.G. Jung
