Feedback doesn’t tell you about yourself. It tells you about the person giving the feedback. In other words, if someone says your work is gorgeous, that just tells you about *their* taste. If you put out a new product and it doesn’t sell at all, that tells you something about what your audience does and doesn’t want. When we look at praise and criticism as information about the people giving it, we tend to get really curious about the feedback, rather than dejected or defensive.
