This document discusses how to build and sustain trust. It defines trust as choosing to risk making something you value subject to another person's actions. Distrust is when you choose not to make yourself open to another's actions due to a perceived lack of safety. The key competencies for building trust are sincerity, reliability, competence, and care. Sincerity involves honesty and alignment between words and actions. Reliability means keeping commitments and promises. Competence is having the ability and skills to do one's job. Care is having others' best interests in mind as well as shared interests like team success. Building trust requires demonstrating these competencies consistently over time.
