How do you handle a negative feedback

I do believe that an important skill to achieve success in life is learning how to respond to feedback from people around us. Positive feedback is a gift and negative feedback might be a nightmare. Based on my own experience of getting a negative feedback . I just take it and I challenge myself. However , eventthough it caused me pain- I take all of them as a tool to help me imporove the business , my working environment and my relationships to all concern. How about to my fellow mylotters how do you deal with it??
