“It’s brutally hard to tell people when they are screwing up. You don’t want to hurt anyone’s feelings; that’s because you’re not a sadist. You don’t want that person or the rest of the team to think you’re a jerk. Plus, you’ve been told since you learned to talk, “If you don’t have anything nice to say, don’t say anything at all.” Now all of a sudden it’s your job to say it. You’ve got to undo a lifetime of training. Management is hard.”
