Criticism is sometimes helpful.It depends on the relationship between the people,the power balance and whether the one giving it cares about the other.After all we may pay a therapist to listen and while they possibly don’t criticise directly we may learn things we find hard to acknowledge about our self and that if we can study it we may understand our own behaviour better.But that usually takes a long time.Change is hard and so even if we know we have some faults we may not be able to change them.But maybe it’s better if we know.On the other hand criticism often a form of defence.{Attack etc]
The side of ourself we don’t know about is called,The Shadow” in Jungian
psychoanalysis.Sometimes there may be good qualities hidden there.
Of course it all depends on how much we can change.But if you discover you are full of envy then that might explain why you keep no friends for long.We think we know ourselves but we don’t really…judging by dreams I’ve had
