The world will give us feedback and input whether we seek it out or now. People will make comments about our work. It is actually we ourselves who attach the labels "nice" or "negative" to each piece of input. We may not be able to choose our emotive response to each input, but we can choose how we interpret their worth to us, and thus to accept or reject them in a way that supports us. (This does not mean we unthinkingly dismiss every input that does not immediately support our world-view.)
