The only people who never hear criticism are those who never hang around other people or react so horribly to it that people stop being honest and walk on eggshells all the time around them. It's a very lonely existence that only brings more feelings of rejection and abandonment. Not all criticism is equal. Some is benevolent and some malevolent. You have to surround yourself with people who bring the former. They are the truly good people you want to be like.
