Never give chance to a person for comparing you and him/third person. Cause: Most of them will try to highlight your negative things and drawbacks. So there are chances to goes down your confidence and commitments...... You can compare yourself with another, and then only u can realize which one is good or bad and according to that you can prepare your mental health....
Life is like dancing. If we have a big floor, many people will dance. Some will get angry when the rhythm changes.
