View feedback as a shortcut to success. If you only see feedback as criticism and shut down, you will limit your growth potential. If someone is being honest with you and helping you realize what needs to be improved upon, use that to your advantage. Either way the information is still there and it is still true. You can choose to ignore it and continue to be substandard at whatever it is they mentioned, or you can do something about it. This will also reinforce others to continue to give you feedback. It may not always feel the best, but you will always know where you stand.
