There is usually one conversation you are putting off. The feedback that needs to land. The boundary you keep not setting. The thing your co-founder, partner, or parent has been waiting for you to say. The cost of avoiding it is not zero, and you know that, which is part of why you are stalling. These books are for that one talk. They cover how to disagree without breaking the relationship, how to listen so the other side stops bracing, and how to tell whether the conflict is about the thing on the surface or something else entirely. Read one before the talk. The talk will be different.
