Have a lot of confidence in yourself so that when you are hurt you do not seek revenge. It is not necessary for you to prove that you are better or that you are right. There is no point in hurting them; you will not win want nothing Let them think what they want to think. Let them act how they want to act. Don't let it worry you. If you know who you are, then what they do or say will not affect you. Just block access to you and continue to prosper.
