Julie Zhuo: We all feel a pit in the stomach when we have to tell others that they aren’t doing as well as they should. She says giving feedback is as much about singing praise that comes off easily as it’s about giving constructive criticism that makes you uncomfortable. The biggest lie to fail to deliver the right kind of feedback is an act of rationalization, an excuse most of us in this position have told ourselves. It will take practice, many, many hours of failed conversations, she says.
