Constructive criticism is a funny little thing. Most people believe that they accept criticism or feedback well but in my experience as a manager I have seen people struggle with it. None of us were made perfect and we all are prone to falter from time to time. Feedback from our loved ones or superiors is virtually the only way to know what needs to change in order to grow and develop into the people we have the potential of being. Often times the key to success lies in our adaptability to change and our ability to accept feedback.
