Matthew Donnelly said this quote

Criticism of others. Criticism of 'self'.Criticism is the lack of compassion, insecurity of 'self' there a self defense mechanism is to put others down to feel superior EVEN IF you disagree with their lifestyle. Let go of your 'Self'.And if you have acted wrongly according to your own self-standard. Let go of your 'self'.Recognize when others are criticizing and 'choose' not to conform to the unconscious acts of others. Be aware, let go.
