How to handle Criticism

Often we have to face criticism from different set of people for what we are doing. Sometimes it is having some improvement advice along with pin pointing the mistakes we have done. We need to handle the criticism carefully. Reacting or overreacting may spoil relationships and image also. People may forget what someone else done to you or what was the actual reason for you to behave in such a way, they will just remember how you behaved or reacted in that situation. This will create an image of you in their mind and they will always remember you with that image even though it was a one off kind of behavior. Also whenever these kind of people talk about you, they portray the same image of you everywhere. So need to be very careful while handling the criticism and reacting or responding to that.
