How to accept criticism
Stay calm.
It is natural to feel defensive when you are being criticized, but allowing yourself to get upset and show your emotions will not help the situation. Keep in mind that we all make mistakes when we are learning a new skill, so criticism is inevitable and if you deal with it in a constructive way you may learn something valuable as a result.
So try to stay calm even if the person who is criticizing you seems agitated. Do not match their emotions because it may make you seem incapable of handling criticism and it will interfere with your ability to learn something from the criticism.
